%X The dependence of the Dewar resonance energy (DRE) on the Kekul¨¦ structure count (K) was found to be significantly different from that earlier anticipated. Within classes of benzenoid isomers, the DRE increases either as Kl for l ~ 0.3 or as (ln K)l for l ~ 2. Both functional dependencies result in approximate expressions for DRE of nearly equal accuracy. Approximations of the form DRE ~ a K + b and DRE ~ a' ln K + b' are somewhat less accurate, but can still be used in usual practical applications of the Dewar resonance energy.
