Typesetting chemistry in LaTeX

Yesterday I gave the following tip on TeXtip:

Set chemical formulas with math Roman. Example: sulfate is $mathrm{SO_4^{2-}}$

TorbjoernT and scmbradley let me know there’s a better way: use Martin Hansel’s package mhchem. The package is simpler to use and it correctly handles subtle typographical details.

Using the mhchem package, sulfate would be written ce{SO4^2-}. In addition to chemical compounds, mhchem has support for bonds, arrows, and related chemical notation.







\ce{CO2 + C -> 2CO}

\ce{SO4^2- + Ba^2+ -> BaSO4 v}



For more information, see the mhchem package documentation.

  1. Thanks, John, for posting this! I was having trouble finding any documentation on the mhchem package. Now my nuclear reaction notation looks just right.

  2. Hi,
