The linear dependence, previously claimed, of the total -rr-electron energy (E~) of isomeric benzenoid hydrocarbons on the number of Kekul6 structures (K) is found to be a satisfactory approximation only for benzenoids having eight or fewer six-membered rings (h ~< 8), and is violated if h >1 9.

It is known that an alternative algorithm to the Gordon-Davidson algorithm for counting the Kekule valence structures of catacondensed non-branched benzenoid hydrocarbons is a reformulation of the original algorithm. Recently an alternative algorithm [ 1,2] to the Gordon-Davison (GD) algorithm [ 31
There are series of C,H, formulae for fully benzenoid hydrocarbons which correspond to equal numbers of all-benzenoid isomers. These formulae are treated in general terms. Also, other classes of all-benzenoids are defined in relation to a periodic table for fully benzenoid hydrocarbons. Some new enu
