Intramolecular Radiationless Transitions

In this paper we consider a theory for intramolecular radiationless transitions in an isolated molecule. The Bom-oppenheimer zero-order excited states are not pure in view of configuration interaction between nearly degenerate zero-order states, leading to the broadening of the excited state, the line shape being Lorentzian. The optically excited state can be described in terms of a superpositi...

Medium-induced radiationless transitions and effect of solvent on radiationless transitions.

The purpose of this paper has been to investigate the effect of solvent on radiationless transitions. Two types of the solvent effect have been studied: one is the so-called medium-induced radiationless transition, i.e., the radiationless transition induced by the interaction between the solute and solvent, and the other is the effect of solvent on the radiationless transition through the chang...

Radiationless transitions and photochemical reactivity

The potential energy along a reaction coordinate can be calculated in terms of the reaction energy, the force constants and the equilibrium bond lengths of the reactive bonds, the bond order at the transition state and, for very exothermic or endothermic reactions, the so called "configuration entropy". Such potential energy curves allows one to assess the importance of quantum mechanical tunne...

Null-field radiationless sources: comment.

We elaborate on a recent paper by Hurwitz and Gbur [Opt. Lett.39, 6529 (2014)], dealing with null-field sources. After commenting on their theory in Minkowski space, we show how the theory can be conveniently generalized to the case of curvilinear space.
