The 248 nm photodissociation of DOCl: laser excitation fluorescence spectra of OD
The 248 nm photodissociation of DOCl: laser excitation fluorescence spectra of OD
The dynamics of the 248 nm excimer-laser-induced photodissociation of DOCl has been investigated by the observation of the OD fragment by laser excitation fluorescence. The OD PI(A') lambda doublet state is strongly favoured in the dissociation and there is a small preference for the 2-PI-3/2 spin-orbit state. The observed OD rotational distribution differs for the two lambda doublets, and for the PI(A') component of the 2-PI-3/2 spin-orbit state the distribution is Gaussian. The results are interpreted in terms of a fast dissociation with most of the energy released into relative translational energy. The rotational distribution can be explained with a Franck-Condon type model.

Abstract
The dynamics of the 248 nm excimer-laser-induced photodissociation of DOCl has been investigated by the observation of the OD fragment by laser excitation fluorescence. The OD PI(A') lambda doublet state is strongly favoured in the dissociation and there is a small preference for the 2-PI-3/2 spin-orbit state. The observed OD rotational distribution differs for the two lambda doublets, and for the PI(A') component of the 2-PI-3/2 spin-orbit state the distribution is Gaussian. The results are interpreted in terms of a fast dissociation with most of the energy released into relative translational energy. The rotational distribution can be explained with a Franck-Condon type model.
