% \section{Introduction}
%
% This collection of bibtex style files started with a version intended for
% \emph{Chem.\ Eur.~J.} The base version of it was created using the
% marvelous |makebst| program by Patrick W.~Daly. Soon afterwards, a version for
% \emph{J.~Am.\ Chem.\ Soc.}\ was available, too. With changes to both files
% becoming more and more complex, everything was merged into a single
% |chembst.dtx| file to avoid maintaining several versions of the code. Using
% the |docstrip| utility, the different style files can now easily be generated
% by running |latex chembst.ins|.
% Currently, the following journals are supported:
% \begin{itemize}
%   \item \emph{Chem.\ Commun.}\ (|ChemCommun.bst|)
%   \item \emph{Inorg.\ Chem.}\ (|InorgChem.bst|), which can be used for
%     most of the journals published by the American Chemical Society
%   \item \emph{J.~Am.\ Chem.\ Soc.}\ (|JAmChemSoc.bst|)
%   \item \emph{Chem.\ Eur.~J.}\ (|ChemEurJ.bst|), which can be used for most of
%     the journals published by Wiley
% \end{itemize}
% Additionally, the following styles are also supported:
% \begin{itemize}
%   \item \emph{Curriculum vitae} (|cv.bst|), a style similar to \emph{Chem.\
%     Eur.~J.} that includes the title of an article
% \end{itemize}
%
%
%
% \section{Some notes}
%
% \subsection{crossref entries}
% \label{o::crossref}
%
% The crossref feature is described in detail in the |btxdoc.dvi| \BibTeX\
% documentation. Using crossref is a way to inherit information from a parent
% entry. As an example consider a database containing a @book entry for citing
% the whole book and a @inbook entry for citing some pages from that book.
% Naturally, the only difference between both entries is that @inbook contains
% a |pages| field. All the other information is stored redundantly.
%
% Using the crossref feature the @inbook entry can be as simple as
% \begin{verbatim}
%   @inbook{inbook_key,
%     crossref = {book_key},
%     pages = {1-5},
%   }
% \end{verbatim}
% All the other fields (author, publisher, year etc.) are inherited from the
% parent entry with the key |book_key|.
%
% If you do not cite the whole book in your document, i.\,e.\ the document does
% not contain |\cite{book_key}|, the following will happen. If |book_key| is
% not cross-referenced more than once\footnote{%
%   You can change that number by passing the argument |-min-crossrefs=number|
%   to bibtex.}
% everything will look perfectly like a ``normal'' @inbook entry. However, if
% |book_key| is cross-referenced more than once, the entry corresponding to the
% whole book will be added automatically to the bibliography and the @inbook
% entry will be formatted as A. Author in |\cite{book_key}|,
% pages 1-5.\footnote{%
%   In fact \cs{bibliographycite} is used. See section~\ref{o::customization}
%   for details.}
% If your document does contain |\cite{book_key}| you will always get the
% crossref format.
%
% This applies to entries of type @inbook, @incollection and @inproceedings.
%
%
%
% \subsection{JAmChemSoc.bst}
%
% The Journal of the American Chemical Society (ACS) now requires
% that for citations with more than 10 authors the list of authors is
% abbreviated by giving only the first author followed by \emph{et al.} The
% style file |JAmChemSoc.bst| automatically takes care of that. However, ACS
% also
% requires that for those citations the full list of authors should be given as
% Supporting Information. The style |JAmChemSoc_all.bst| can be used for this
% purpose, since it does not abbreviate the list of authors.
%
%
%
% \subsection{Customization}
% \label{o::customization}
%
% Defaults for several commands used in the |thebibliography| environment are
% defined at the beginning of the |.bbl| file. To override the default settings
% define the command before using the \mbox{\cs{bibliography}} command.
%
%
% \DescribeMacro{\url}
% The \cs{url} command is used to display urls. By default this only selects a
% typewriter font. However, it is strongly recommened, that you use the package
% |url.sty| which defines \cs{url} in a more sophisticated way. Due to some
% problems with multiline urls (spurious '\%' in formatted url) you should use
% some reasonable new version (3.2 works fine) of |url.sty|.
%
%
% \DescribeMacro{\urlprefix}
% Every \cs{url} is prefixed by \cs{urlprefix}. By default \cs{urlprefix} does
% nothing. This command is useful if you have to prepend every url with some
% text. For \emph{Angew.\ Chem.}, i.\,e., every url must be preceded by ``to be
% found under''. This can easily be achieved by giving
% \begin{verbatim}
%   \newcommand{\urlprefix}{to be found under }
% \end{verbatim}
%
%
% \DescribeMacro{\foreignlanguage}
% This command is used to temporary switch the language for the title of books
% etc. By default this does nothing but if you load |babel.sty| then the
% language will be changed.
%
%
% \DescribeMacro{\bibliographycite}
% This command is used for formatting crossref entries. It defaults to
% \cs{cite}. However, if you use |overcite.sty| you may not want superscripted
% citations in your bibliography. Then you can define \cs{bibliographycite} the
% following way
% \begin{verbatim}
%   \newcommand{\bibliographycite}[1]{[\citen{#1}]}}
% \end{verbatim}
%
%
% \DescribeMacro{\bbl*}
% Inside the |.bbl| file no text is hard coded and instead the appropriate
% \cs{bbl*} command is used. The text ``erratum'', i.\,e., is produced by
% \cs{bblerratum}. Thus one can easily change all the words in the bibliography
% by defining the appropriate commands.
% \begin{verbatim}
%   \newcommand{\bblerratum}{\emph{errat.}}
% \end{verbatim}
% for instance will give ``\emph{errat.}''. By redefining all necessary commands
% you can also change the language to some other language than the default
% english.
%
%
%
% \section{Description of important entry types}
%
% The entry types discussed in this section are those which are most commonly
% used in writing articles in chemistry. The types listed here refer to entries
% in the database (i.\,e.\ |*.bib|).
%
%
%
% \subsection{@article}
%
% This entry type is designed for an article in a journal.
% The entry type has been augmented with several additional fields. Other style
% files will simply ignore these fields. The following fields are recognized:
%
% \begin{description}
%   \item[author] The names of all authors
%   \item[journal] The name of the journal the article was published in
%   \item[year] The year the article has been published
%   \item[volume] The volume this article has been published in
%   \item[pages] The page numbers of the article
%   \item[eid] The electronic identifier of an article. Some journals, i.\,e.\
%     \emph{J.~Chem.\ Phys.} no longer have page numbers associated to an
%     article but only use the EID. If an EID is present |pages| will be
%     ignored.
%   \item[numpages] The number of pages of an article. This will only be used
%     together with an EID.
%   \item[germanpages] When citing articles from \emph{Angew.\ Chem.} one
%     should always give both the german and the english version. If this
%     field is present the style file assumes that this is a citation of
%     \emph{Angew.\ Chem.\ Int.\ Ed.} and automatically appends the correct
%     citation for \emph{Angew.\ Chem.} The year is always the same for
%     both versions and the german volume is easily calculated by adding 73
%     to the english volume. The page range of the german version is taken
%     from the |germanpages| field.
%   \item[erratumyear, erratumvolume, erratumpages, erratumeid,
%     erratumnumpages] If any of these fields is non-empty the information
%     will be used to append a correctly formatted citation of the erratum
%     to the regular citation.
%   \item[note] A free format text that will be appended at the very end of a
%     citation.
% \end{description}
%
%
%
% \subsection{@book}
%
% This entry type is designed for citing a whole book. If you want to cite only
% some chapters or pages of a book use @inbook or @incollection (see below).
% The following fields are recognized:
%
% \begin{description}
%   \item[author, editor] The names of all authors or editors. You can only use
%     one of author or editor, but not both.
%   \item[title] The title of the book
%   \item[language] The language of the title
%   \item[edition] The edition of the book
%   \item[volume] The volume of the book
%   \item[series] The series the book is part of
%   \item[publisher] The publisher of the book
%   \item[address] The publisher's address
%   \item[year] The year the book was published in
%   \item[note] A free format text that will be appended at the very end of the
%     citation.
% \end{description}
%
%
%
% \subsection{@inbook}
%
% This entry type is designed for citing chapters or pages of a book. The final
% format of the citation is the same as for @book except that the cited
% chapter(s) and/or pages are appended. For the crossref feature see
% section~\ref{o::crossref}. The same fields as for @book plus
% the following are recognized:
%
% \begin{description}
%   \item[chapter] The cited chapters
%   \item[pages] The cited pages
% \end{description}
%
%
%
% \subsection{@incollection}
%
% This entry is also designed for citing chapters or pages of a book and thus
% very similar to @inbook. However, there is one difference: the present entry
% is designed for chapter(s) written by some authors in a book edited by
% others. The final citation looks similar to A. Author, in book title, edited
% by E. Editor. The crossref feature is discussed in section~\ref{o::crossref}.
% The same fields as for @inbook (except |title|) plus the following are
% recognized.
%
% \begin{description}
%   \item[booktitle] The name of the book
% \end{description}
%
%
%
% \subsection{@masterthesis and @phdthesis}
%
% These entries are designed for citing a master's thesis or a PhD thesis. Both
% entries are very similar. The only difference is the thesis' name. The
% following fields are recognized:
%
% \begin{description}
%   \item[author] The author of the thesis
%   \item[school] The school or university where this thesis work was carried
%     out.
%   \item[address] The school's address
%   \item[year] The year the thesis was finished in.
%   \item[note] A free format text that will be appended at the very end of the
%     citation.
%   \item[url] An url where the thesis can be found.
% \end{description}
%
%
%
% \subsection{@program}
%
% This entry is designed for citing a program. This is a new entry type which
% is not contained in the standard \BibTeX\ styles. It allows greater
% flexibility compared to the @misc entry. The following fields are recognized:
%
% \begin{description}
%   \item[author] The program's authors
%   \item[title] The program name
%   \item[description] A short description of the program
%   \item[version] The version/release of the program
%   \item[year] The year the program was published in.
%   \item[publisher] The publisher of the program
%   \item[address] The publisher's address
%   \item[note] A free format text that will be appended at the very end of the
%     citation.
%   \item[url] An url where the program can be found.
% \end{description}
%
%
% \subsection{@misc}
%
% This entry is designed for everything that does not fit into one of the other
% entry categories. This is for instance useful to cite websites. The following
% fields are recognized:
%
% \begin{description}
%   \item[author] The author of the cited work
%   \item[title] The title of the cited work
%   \item[howpublished] A free format text describing how this work has been
%     published. This is usually empty.
%   \item[year] The year the cited work was published in.
%   \item[note] A free format text that will be appended at the very end of the
%     citation.
%   \item[url] An url where the cited work can be found.
% \end{description}
%
%
%
% \subsection{@unpublished}
%
% This entry is designed for unpublished results. The following fields are
% recognized:
%
% \begin{description}
%   \item[author] The author(s) of the unpublished work
%   \item[title] The title of the unpublished work
%   \item[year] The year the unpublished work was carried out.
%   \item[note] A free format text explaining what kind of unpublished work
%     this is (i.\,e.\ ``unpublished results'').
%   \item[url] An url where this work can be found.
% \end{description}
