The optical activity of 2.2′-spirobiindane-1.1′-dione

Abstract

From the circular dichroism of optically active 2.2′-spirobiindane-1.1′-dione and its precursor in several solvents as well as from the liquid crystal induced circular dichroism in connection withPPP-type calculations can be concluded that the optical activity of the n—π* is best understood in terms ofWeigang's generalized vibronic scheme; the n—π* can be rationalized on the basis of the coupled oscillator theory.
