Anisotropic light scattering by solutions of large macromolecules oriented in the intense electric fields of laser beams

Abstract

SYNOPSISLight scattering by monodispcrsc solutions of rigid anisotropic rod-like macromolecules of length 1. of the same order as the wavelength A. reoriented in the strong electric field of linearly polarized laser light is discussed. This discussion is based on numerical calculations of the relative variations in intensity h H Y , 6 H P . 6Vy. 6Vb. of the light scattering components, induced by a laser beam of high intensity I? polarized horizontally or vertically to the plane of observation. Calculations are made for various values of 9 ! : " ( w~) = [(upLa;L)I!:'/2kT] (the reorientation parameter of the optical polarizability ellipsoid with principal polariiabilitics aYL. arL for the laser frequency w L ) and for the threc values / / A = 0.5, I . and 2.
