On Tue, 26 Apr 2005 Martin Hensel submitted an update to the
mhchem
bundle to CTAN.
Location on CTAN: macros/latex/contrib/mhchem/ Summary description: for typesetting chemical formulae, chemical equations and Risk and Safety (R and S) Phrases License type: lppl
Announcement text: ---------------------------------------------------------------------- This is an update to version 2.00.
The mhchem bundle consists of two packages: mhchem and rsphrase.
The mhchem package provides commands for typesetting chemical molecular formulae and equations. What's new? - a new versioning system that tries to incorporate old and improved syntax into one file. (usepackage[version=2]{mhchem}) - the command cee which can take & and \ as input, for use in equation environments - ce now works in text mode as well - new symbol added: ^. - basic support for bonds: A-B=C#D - math inside formulae can be achived using cmath - new option for reaction arrows: ->C[+H2O] is a shortcut for ->[ce{H2O}]
The rsphrase package contains the text of all official Risk and Safety (R and S) Phrases that are used to label chemicals. At the time being, these phrases are available in Englisch, Danish, French and German (current spelling).
What's new? - French phrases. Thanks to Dominique Richard for his work. - bugfixes ----------------------------------------------------------------------
Thanks for the update.
