โœฆ Synopsis

A method for the estimation of E,,, the number of benzenoid systems with h hexagons, is presented. B,, is predicted to lie between 3.200x lo6 and 3.202x 106. This is a significant improvement on the earlier result which located BI1 between 3.080~ lo6 and 3.300x 106.

There are series of C&H, formulas for benzenoid hydrocarbons which correspond to equal numbers of isomers. General expressions (in two schemes) are reported for these formulas. The numbers of isomers for these constant-isomer series are treated by a combination of mathematical analysis and computer-

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
