SPECTRAL DISTRIBUTION OF LIGHT SCATTERED FROM ONCE-BROKEN RODS

The spectral distribution of light scattered from monodisperse, infinitely dilute solutions of optically isotropic, once-broken rods is calculated. It is assumed that the break occurs in the middle of the rod and that it acts as a universal joint about which the two segments independently undergo rotational diffusion with identical rotational diffusion coefficients. The integrated scattered intensity is calculated as well as the contributions to this intensity of the pure translational diffusion term and the first few terms whose spectral distribution depends on both the rotational and translational diffusion coefficients. The results are compared to those previously obtained for the rigid rod. © 1969, American Chemical Society. All rights reserved.
