Abstract

The photochemical reaction of 2-(bromomethyl)naphthalene (2-BMN) in acetonitrile solution was studied with nanosecond laser flash photolysis. There appeared two peaks at 380 and 415 nm in the transient absorption spectrum obtained at a 248 nm excitation, while a 308 nm excitation gave only one peak(380 nm), which is due to naphthylmethyl radical. The absorption at 415 nmis attributed to the T-T absorption of 2-BMN by means of triplet photosensitization with benzophenone. The excitation energy effect on the reaction reveals the different relaxation and reaction dynamics of the S-1 and S-2 states, which are discussed in terms of a dissociative and non-dissociative triplet state.
