SOLVENT CAGE SPECTROSCOPY

Potential functions for photodissociation, excited state intramolecula r torsion, and excited state twisting-intramolecular-charge-transfer a re discussed in terms of sensitivity to solvent cage perturbation. A s pectroscopic solvent cage theory based on a Born-Oppenheimer quantum m echanical framework is used for the justification of adducing viscous flow barriers as perturbations to the intrinsic molecular potentials. Experimental correlation of new spectroscopic phenomena is presented f or each of the three potentials under perturbation.
