✦ Synopsis

A novel modification of the forced Rayleigh scattering method for determining the translational diffusion coefficient and lifetime of photochromic moieties is effected through imposition of a nonsinusoidal transient optical sating flOt.2) to a condensed medium sample. A multiple~rder diffraction pattern is observed and subsequent analysis of the exponential decays of higher+xder diffraction spots reveals that they originate from the higher-order spa&l Fourier components of TOG.

On the basis of a recent theory, we present a detailed analysis of initial state consequences on transient grating (and Ronchi ruling) signals. We show explicitly that the required changes in the interpretation of data, while substantial in principle, are of no practical importance in experiments re
