| Abstract: | Transient grating measurements on sample with an anisotropy or with multiple excited states are described. The general formula for the intensity of the diffracted light from a transient grating in a sample with an anisotropic diffusion coefficient is presented and is applied to CdS. A transient grating spectroscopic technique for a sample with multiple excited states is discussed in detail. In addition to these, the contribution of a population and a thermal grating to the observed signals is discussed. |
