Nonlinear Optical Properties of Polyenes: Electron Correlation and Chain Conformation

Abstract

ABSTRACTUsing a recently developed many-electron theory of second and third order nonlinear optical susceptibilities, microscopic descriptions of γxxxx(-3ω;ω,ω,ω) are presented for two conformations of polyenes. The importance of electron correlations and the effects of variation in conformation and chain length are discussed.
