Paper Abstract

Non-resonant, electronic components of static and dynamic third-order molecular polarizabilities (y) for ethylene, linear polyenes, and benzene are calculated. The specific dynamic polarizabilities treated are those for the third-order nonlinear optical processes of third-harmonic generation and electric-field-induced second-harmonic generation. Also calculated are one- and two-photon spectroscopic properties of the 1ππ* states salient to the π-electronic component of y(yπ). The yπ's for the linear polyenes are defined principally by chain-axis-polarized virtual electronic transitions between three states: (1) the ground state, (2) the strongly one-photon allowed 1"1Bu"ππ* state, and (3) a strongly two-photon allowed n"1Ag" (n>2) ππ* state.
