✦ Synopsis

Tie-resolved coherent anti-Stokes Raman experiments are reported for the benzene crystal 991 cm-' mode and in mixed C,H,/CeD, crystals. Addition of C,D, results in an increase in the rate at which the excitation is trapped-This is explained by the recent theory of Velsko and Hochstrasser which predicts that the trappinz rate should undergo a msaimum at some isotopic impurity concentration, consistent with observations from time and frrquency domain studies. A proper convolution procedure for CARS experiments in the time domain is presented.
