Abstract

By using femtosecond transient absorption measurement techniques, we have investigated the decarbonylation of diphenylcyclopropenone (DPCP) in several solutions. The short lived transient absorption band which can be assigned to the S n ←S2 transition of DPCP was observed around 470 nm. The lifetime of about 0.3 ps should be essentially determined by the formation of diphenylacetylene in the ground electronic state.
