Molecular Photodissociation Dynamics provides overviews of selected aspects of the subject. The experimental study of photodissociation has opened the way to detailed theoretical study of the fragmentation dynamics of the excited state. This book will therefore be essential reading for those working in this area. As a molecular mechanism of dissociation dynamics under external influence (Figure 1), the photon excites the molecule from the ground to a higher electronic state; the dissociation of the excited complex only occurs if the potential of the upper electronic state is repulsive along the intermolecular coordinate. Dynamics of Molecular Photodissociation. Abstract. Photodissociation is the break-up of an initially bound (diatomic or polyatomic) molecule through the absorption of light. If the dissociation energy is small (≲ meV) as it is usually the case for van der Waals molecules, for example, an infra-red (IR) photon is sufficient to break the weak by: 2. Photodissociation induced by the absorption of single photons permits the detailed study of molecular dynamics such as the breaking of bonds, internal energy transfer and Author: Reinhard Schinke.
Abstract: Photodissociation is the dominant removal process of molecules in any region exposed to intense ultraviolet (UV) radiation. This includes diffuse and translucent interstellar clouds, dense photon-dominated regions, high velocity shocks, the surface layers of protoplanetary disks, and cometary and exoplanetary atmospheres.
