Relaxation photochemical

Figure 14 Illustration of the general procedure used to locate the initial relaxation direction (IRD) toward the possible decay products, (a) General photochemical relaxation path leading (via conical intersection decay) to three different final structures, (b) Potential energy surface for a model elliptic conical intersection plotted in the branching plane, (c) Corresponding energy profile (as a function of the angle a) along a circular cross section centered on the conical intersection point and with radius d.

Kaplan and Wilzbach further explored benzvalene formation following 2536 A excitation of benzene at high pressures, and their communi-eation is an elegant description of the experimental intricasies associated with establishing quantum yields of photochemical relaxation channels in...

The photochemical relaxation method enqployed in this work initiates a chemical reaction by the direct absorption of light into one of the reacting species (1). In contrast, the temperature and pressure-jump techniques perturb the position of equilibrium by changing the conditions of the reaction medium (2), The photochemical dissociation method thus has several inherent advantages over the ten5>erature-jump and related relaxation methods...
