Abstract
The photochemistry and the irreversible photodecomposition of naphthac enequinones have been studied. Picosecond, nanosecond, and longer live d transient spectra have been recorded and the kinetics of the interme diates measured and assigned to specific transient species. On the bas is of the data, a mechanism for the photoinduced structural rearrangem ent is proposed. The adiabatic reaction is found to proceed via triple t states and the irreversible decomposition due to excited triplet abs traction of hydrogen from the solvent.
