chemarr

Arrows for chemists.

Very often chemists need a longer version of reaction arrows (`\rightleftharpoons`) with the possibility to put text above and below. Analogous to amsmath's `\xrightarrow` and `\xleftarrow` this package provides the macro `\xrightleftharpoons`. The package requires amsmath. To use it, `\usepackage{chemarr}`, then `\xrightleftharpoons[below]{above}` .

The package is part of the oberdiek bundle.
