    The classical theory of the rate of unimolecular isomerization developed by Gray and Rice is extended in two ways. First, an improved state dependent approximation to the system separatrix is introduced. Second, a systematic approximation for the rate of intramolecular energy transfer in one...

    Laser induced fluorescence spectra of expansion-cooled NO2/Ne samples (1 and 2 K) are reported for transitions that originate from the lowest rovibronic levels and terminate on levels near D0. At 1 K, nearly all transitions originate from N‘=0. With the present resolution of 0.02 cm-1, the...

    The statistical theory of arbitrary unimolecular reactions is developed with an ergodic theoretic basis. In the process, unimolecular kinetics is derived from dynamics, in terms of well-defined mixing and time-scale assumptions. The statistical theory is then taken beyond kinetics via the new...
