Abstract
The dynamics of the photodissociation of small molecules is discussed in view of a few recent experiments to demonstrate the state of the art in this field. The highly improved understanding of photodissociation processes is essentially due to modern experiments in which the product motion is analysed in great detail by state selective detection methods. In this contribution an effort is made to understand the origin for this motion in terms of the strength of final state interaction. Using the photodissociation of water in the first absorption band as an example, it is shown that in the case of weak final state interaction product motion arises essentially from parent motion. In the case of strong final state interaction additional product motion is generated during the fragmentation by forces that originate from anisotropies of the excited state potential surface. Particular efforts are made to understand the origin for the selective population of A-doublet states.
