Sažetak

The hybridization in methylene biscyclopropylidene, 1,1'-dimethylene
biscyclopropylidene, and 1,2-dimethylene biscyclopropylidene
is considered by applying the method of maximum
overlap. The results show variations in hybrids describing exocyclic
double bonds: for ring carbons from sp~.ss to sp2-85, and
for off-ring carbons from sp1-10 to sp1-41, depending on the immediate
surounding. Bond overlaps for C=C consequently vary
somewhat, the largest bond overlap being of the central C=C
bond connecting two three membered rings. The results of the
maximum overlap calculations are compared with available
experimental data.
