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 non-sinusoidal transient optical grating (TOG) to a condensed medium sample. A multiple-order diffraction pattern is observed and subsequent analysis of the exponential decays of higher-order diffraction spots reveals that they originate from the higher-order spacial Fourier components of TOG.
