Theoretical and Experimental Studies of Molecular Dynamics
Abstract
We describe a single-sideband frequency demodulation scheme with large dynamic range which gives linear response and is capable of shot-noise- limited performance when used with time-resolved pump and probe, polarization, and three- and four-wave mixing spectroscopies. An extensive examination of the vibrational state dependence of fluorescence lifetimes in supersonic jet-cooled 1B2u benzene, and the inferred vibrational state dependence of the non-radiative rate constants, are reported. The qualitative features of our results agree with those obtained from previous investigations using room temperature vapor phase samples. The spectral simplification achieved in the supersonic jet expansion has, however, allowed measurement of the fluorescence lifetimes of a number of 1B2u vibrational levels not previously studied.
