โœฆ Synopsis


A critical comparison is made between a theoretical model for photochemical reactions based on their analogy with radiationless transitions and the experimental data on hydrogen abstraction by excited ketones in solution. It is concluded that rapid vibrational energy redistribution tends to rule out mcchanisrns based on energy transfer to a particular vibrational mode, except in I&v-pressure gases.

It is found that the triplet-triplet energy transfer (ET) reaction between triplet benzophenone ('BP\*) and l-naphthol (ROH) is competitive with the hydrogen atom abstraction (HA) reaction. The rate constant of ET is enhanced with an increase of solvent polarity while that of HA is reduced. A possib

The vibrational energy relaxation (VER) of polyatomic molecules has been the central issue in many of the chemical reactions in condensed phase [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] as well as in gas phase . The vibrational energy introduced to the molecule is immediately redis
