Paper Abstract

The first hyperpolarizabilities, (beta) , of bacteriorhodopsin, retinal, and related molecules were determined experimentally by using the hyper-Rayleigh scattering technique and compared to the calculated values obtained with the semiempirical intermediate neglect of differential overlap/configuration interaction/sum-over-states method. The experimental and theoretical results are in excellent mutual agreeement. The hyper-Rayleigh scattering technique is shown to be very sensitive to the degree of solubilization of bacteriorhodopsin. Theoretical and experimental data confirm the expected dependence of (beta) on the first transition energy as well as an exponential increase of (beta) with the number of double bonds. It was found that, upon trans to 13-cis or 9-cis isomerization of a retinal double bond, a constant fraction of the (beta) value is lost, regardless of the nature of the electron withdrawing group or the solvent of choice.
