✦ Synopsis

The role played by solvent in the reactions of organic molecules is not well understood. One is often tempted to try to interpret solvent effects on processes in which ions or molecules are formed solely in terms of solvent interactions with an ionic or radical-like transition state to the neglect of the possible contributions of ground-state factors. The importance of ground-state considerations in ion formation in certain solvolyses has, however, recently been amply demonstrated by Arnett and coworkersl. We wish to report results frcm'a study of a free radical dissociation in which both ground-and transition-state effects seem to require interpretation.

The reaction studied is the thermal decomposition of phenylazotriphenylmethane, I.
