Biphcnylcnc in various solvents is investigated by picosecond time-resolved absorption spectroscopy. The time dependence of the spectral shape of the vibrationally hot S.-S, absorption was analyzed by using the Urbach relation. Vibrational energy flow to the solvent molecules in the surroundings fro

โฆ Synopsis
A new technique IS presented to study translation-to-vibrational (T-V)
energytransfer and tradationaiiy enhanced reactive events_ The method utilizes evcimer laser photobss to produaz transiationalIy "hot" atoms and tirne-resAved in&ared detection of specific exated states_
