Paper Abstract

The hyper Rayleigh scattering (HRS) method was applied to determine the absolute value of second-order hyperpolarizabilities ((beta) ) of stilbazolium p-toluenesulfonates and related ionic species in methanol. In general, the (beta) values of stilbazolium derivatives become large with increasing wavelength of absorption maximum and are 1.1 X 10-28 - 3.9 X 10-28 esu, i.e., 3 - 10 times larger than (beta) of p-nitroaniline. By way of exception, halogenated stilbazoliums showed rather larger (beta) compared with the unsubstituted stilbazolium having almost the same absorption cutoff and maximum. The calculated d value of hydroxystilbazolium p-toluenesulfonate obtained using the present (beta) and the known crystal structure agreed well with the experimental d value by the Maker fringe method.
