Chemistry
Saturday 5th March 2005
Chemists do make use of 
but they have different typesetting conventions from mathematicians. For example the chemical 
is quite different from the mathematical 
. Martin Hensel’s mhchem package allows the easy typing of chemical symbols. Here are some examples taken from mhchem’s documentation. Needless to say, not being a chemist, they don’t mean much to me 🙂
Hover over, or click on a formula, to see the underlying latex code.
