The Use of Holography to Investigate Reactions from Higher Excited States. Action Spectrum of the Second-Photon Step in the Two-Photon Dissociation Reaction of Carbazole.

Abstract

A holographic technique has been used to investigate photochemistry that occurs from higher excited triplet states (i.e., T2, and above). Specifically, the two-photon dissociation of carbazole in poly(methyl methacrylate) films has been investigated. The photochemical action spectrum of the second-photon step is found to be in good agreement with the carbazole triplet-triplet absorption spectrum. This implies that the quantum yield for photodissociation is independent of photon energy in this wavelength region. (Author)
