General theory of rotational excitation for

In this section we extend the theory of photodissociation and rotational excitation outlined in Section 3.2 for J = 0 to general angular momentum states J 7 0 of a triatomic system ABC. We will closely follow the detailed presentation of Balint-Kurti and Shapiro (1981) [see also Hutson (1991), Glass-Maujean and Beswick (1989), Beswick (1991), and Roncero et al. (1990)]. The discussion in this section is not meant to be a substitute for reading the original literature we merely want to outline the general methodology and underline the complexity of the theory.

The theory of rotation effects on prolate luminescent molecules in solution and its experimental verification have been developed and compared. Generalized diffusion equations for the rotational motion of an asymmetric rigid motor have been used to given an expression for steady-state fluorescence depolarization. " The radiationless transition from the first excited singlet state of Eosin has been measured by optoacoustic relaxation, and the absolute fluorescence quantum yields of organic dyes in poly(vinyl alcohol) have also been measured by the photoacoustic method. The accuracy of the method has been discussed in the latter paper. Actinometry in flash photolysis experiments has been assisted by new measurements on the extinction coefficient of triplet benzophenone. Matrix-isolation fluorescence spectrometry has been used to detect polycyclic aromatic hydrocarbons from gas chromatography. ...
