Abstract
Heterodyne-detected transient grating experiments on the OH-stretch mode of HDO dissolved in ${\mathrm{D}}_{2}\mathrm{O}$ resolve two distinctly different contributions originating from the initially excited OH stretch and the OD stretch which is thermally activated during the OH population relaxation. It is demonstrated that interference of both contributions greatly affects the outcome of IR photon echo experiments.
