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 unde

Direct picosecond time resolution of dissipative IVR is reported for the first time. For jet-cooled anthracene with Eeb = 1791 cm -\*\_ rhc urm%-zxed fluorescence displays ;t fast decay of ==75 ps\_ while the reLaxed fluorescence displays a corrc spondin!: rise.

The rotational-temperature dependence of the energy-resolved fluorescence, combined with the calculated level density, indicates that the large variations in the rate of the intramolecular vibrational relaxation over a small escess energy in Sr pcrylene is due to the fluctuations in the density of a
