| Abstract: | The relaxation dynamics of matrix isolated CH and CD have been studied using laser-induced time and wavelength resolved spectroscopy. Vibrationally relaxed B(0′-0″) fluorescence occurs following laser excitation both above and below the gas phase dissociation limit. The vibrational relaxation rate in the B state of CH is found to be 4.6 × 106 sec?1 while the corresponding rate in CD is 5.7 × 105 sec?1. The primary accepting mode in the relaxation process is consistent with rotation. |
