Sorry, I thought you were talking about the spacing between F and 6.

Good, but it can be fixed, by changing the definition of
\domolecule to:

\def\domolecule#1%
   {\expandafter\scantokens\expandafter
         {\detokenize{#1\finishchem}}\egroup}

This re-tokenizes the argument (needed because it was grabbed
by \title already before \molecule had a chance to change the
catcodes.)

It is there to trigger a negative italic superscript correction
(TeX doesn't have a primitive for that :-))

That is actually a fairly standard trick, not something I invented
