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 polymethyl 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
