Molecular Formula Search searches by empirical formula, with optional
ranges for each atom count. For example, C6H8O2 would
return chemicals with the empirical formula
C6H8O2. But searching for
C3H(4-6)O(1-2) would search for all of the following
(empirical) formulae:
C3H4O
C3H4O2
C3H5O
C3H5O2
C3H6O
C3H6O2
Like Mass Search, Molecular Formula Search returns a Chemical List result.
