Hi all, I often have to use the mhchem latex package to write chemical formulas, and I have teh following export issue. If I have this in an org file: \ce{ABO_3} \ce{ABO_{3-\delta}} this exports as \ce{ABO_3} \ce\{ABO$_{\text{3-}\delta}$\} The first one is fine, but the second one is not. The nested {} seems to mess it up. Is there a way to get this to export correctly? thanks, John ----------------------------------- John Kitchin Associate Professor Doherty Hall A207F Department of Chemical Engineering Carnegie Mellon University Pittsburgh, PA 15213 412-268-7803 http://kitchingroup.cheme.cmu.edu
