A >chemical formula is nothing more than a mathematical expression. Using mex sounds good. I think that we'll need to start using some cmavo beyond CV and CVV for this, as cmavo space is pretty full, and most of the chemistry operators are different from mathematical ones. The atoms of mathematical expressions are numbers; those of chemical expressions are atoms, as well as numbers. Elements have names which are brivla; they also have symbols, which are one or two letters. Then there are chemical groups, such as CHO and NH2 and CN, which have their own names. Any idea how to encode all this in mex? phma
