Title: The Effect Of Molecular Distortion In The Rates Of Intersystem Crossing S1 {a Figure Is Presented} Tx {a Figure Is Presented} S0 Processes
Author: Lin C.T.
Stikeleather J.A.
Abstract: It is shown that the interpretation of the experimental observations of Dewey and Hadley that led to the conclusion of the unexpectedly inefficient intersystem crossing S1 {A figure is presented} Tx process in 9,10-phenanthroline, and which prompted a new proposal by Azumi for the mechanism of intersystem crossing in N-heterocyclics is incorrect. The intersystem crossing process in aromatic hydrocarbons and the N-heterocyclics is briefly discussed and compared. The results indicate that the out-of-plane molecular distortions enhance the rate of intersystem crossing, S1 → Tx, mainly through electronic mixing and not the vibrational overlap integrals. The lack of phosphorescence emission for 9,10-phenanthroline in hydrocarbon solvents is attributed to a fast non-radiative T1 {A figure is presented} S0 channel resulting from the pseudo-Jahn-Teller effect. © 1976.
