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. It requires amsmath. To use it, \usepackage{chemarr}, then \xrightleftharpoons[below]{above}. This package was implemented by Heiko Oberdiek and catalogued for CTAN.
