I'm working on the Chemwiki Dynamic Textbook Project at UC Davis, California and I've run into a problem.
I need to formulate a symbol containing double harpoons (as in a reversible reaction, e.g. \rightleftharpoons
); however, I need to have text both above and below the harpoons.
I have an image I can email, but I can't post with an image because I'm new to this.
I can find code for \overleftrightarrow
and \underleftrightarrow
, but that's not quite what I need. I need both, on the same expression.
If anyone has a minute to help me, I would greatly appreciate it!
