title: Phosphorescence spectra and triplet state lifetimes of palladium octaethylporphyrin, palladium octaethylchlorin and palladium 2,3-dimethyloctaethylisobacteriochlorin at 77 K.
abstract: The phosphorescence spectra and triplet state lifetimes of palladium octaethylporphyrin (PdOEP), palladium octaethylchlorin (PdOEC) and palladium 2,3-dimethyloctaethylisobacteriochlorin (PdOEiBC) in n-octane Shpolskii matrices at 77 K are reported. The lifetime and T(1)/S(0) origin energy of each complex are: PdOEP, 1.90+/-0.04 ms, 15162 cm(-1); PdOEC, 0.43+/-0.03 ms, 12547 cm(-1) and PdOEiBC, 0.59+/-0.03 ms, 12863 cm(-1).
