Comparative analysis of electric properties of polyenes,cumulenes, and acetylenes in the method of complete configurational interaction

The dipole polarizability () and the second hyperpolarizability () of -shells in molecules of acetylene, diacetylene, and cumulenes containing from 3 to 6 carbon atoms have been evaluated. It was found that the intramolecular interaction of the -shells substantially decreases the values of in acetylenes and of in cumulenes and acetylenes.Translated from Teoreticheskaya i Éksperimental'naya Khimiya, Vol. 28, No. 3, pp. 243–246, May–June, 1992.
