N2 - From picosecond flash photolysis and spectroscopy, the absorption spectra of the first excited singlet S1 and of the first excited triplet T1 of (OEP)SnCl2 are determined; we also determine triplet quantum yield, φt ≈ 0.80. Similar S1 and T1 phototransient absorption spectra occur in (OEP)Pd. However, two Cu porphyrins show only one phototransient absorption spectrum. Our T1 absorption results are generally consistent with the available earlier spectroscopic studies made with other techniques. Our value for φt lies intermediate between values given by two earlier studies, which were based on two different methods.
