Abstract

The electronic and molecular structure of a series of 1,2-dialkyl (1-3) and 1,2-diphenyl-3-isopropenylcyclopropene (4) have been investigated by means of He(I) photoelectron spectroscopy and ab initio MO calculations. The changes in the lowest energy ionization along the series are interpreted in terms of conformotionally dependent conjugative interaction between the isopropenyl group and cyclopropenyl ring.
