Abstract
The hybnidization in benzocyclobutadiene and benzocyclobutene-
7,8-dimethylene is considered using the method of maximum
overlap. The results show considerable variations of s-p content
of hybrids describing the molecular skeleton. Endocyclic and exocyclic
double bond in four-membered rings in these molecules
exhibit values of deviation angles and bond overlap integrals differing
from those in other examined fused ring molecules1, 2• The
calculated J(C-H) spin-spin coupling constants are in very good
agreement with the available experimental data.
