Kinetic Equations for Orientational Relaxation in Depolarized Scattering

12 2 KINETIC EQUATIONS FOR ORIENTATIONAL RELAXATION IN DEPOLARIZED SCATTERING [Pg.310]

First we consider the symmetry properties of 8aaf(q, t). As we have shown in Appendix 7.B, the polarizability of a symmetric top is given by Eq. (7.B.1). Combining this with Eq. (3.3.4) gives [Pg.310]

It should be noted that a reflection through the xz plane followed by a reflection through the yz plane (or vice versa) reverses the sign of Sayz(q, t) but leaves 8axy(q, t) unchanged. As a consequence of this, the correlation functions f axj,(q, 0) 8ayz(q, t) and f)a yZ(q, 0)Saxy(q, t) ) are zero. Substitution of Eq. (12.2.1) into Eq. (3.3.13) then gives, aside from the multiplicative constant [Pg.310]

It follows from Eq. (12.2.2) that -8aaj(q, t) transforms to eig/lz Saaf(q, t) under the arbitrary translation Az along the z direction, that Saaf(q, t) has even time reversal symmetry, and that 5aaf(q, t) transforms to 5aaf(—q, t) under inversion symmetry. [Pg.311]

Having discussed the symmetry properties of the primary variables 5aap(q, t), let us now pass to the derivation of the relaxation equations that describe evolution of 5a [Pg.311]
