Abstract
The variation of the collisionless absorption spectral shapes for vibrationally excited SF6 and C2F5C1 as a function of the picosecond probe pulse duration was determined using a two-IR frequency pump-probe scheme. The experiments revealed a spectral narrowing with decreasing pulse duration, similar to a recent observation in C3F7I with a single laser pulse. The observed experimental results are shown to be consistent with a dynamic multi-tier classification of energy levels in the QC of polyatomic molecules. Specifically, the time constants for such a coupling are evaluated to be >20 ps for all the molecules studied.
