โฆ Synopsis
A thermodynamic Green's function technique is successfully applied to the calculation of IVR rates of polyatonfic molecul, The energy dependence of IVR rates has interesting threshold features: rates are zero below some critical energy Ec, aJ non-zero for higher energies. This dependence can be understood as a transition from regular to chaotic intramolecular motic

The rates of vibrational energy decay for the S2 excited state of azulene have been measured in both monatomic and polyatomic matrix media at 4 K. We find that the existence of molecular modes in the polyatomic matrix does not substantially affect the rate of energy decay within the S1 vibrational m
