摘要：

Two-colour time-resolved resonance Raman spectroscopy has been used to probe the longest-lived excited state of iron(III) tetraphenylporphyrin (Fe(TPP)Cl). Single-laser (408 nm) irradiation of Fe(TPP)Cl showed that significant depopulation of the ground electronic state could be achieved by use of high power, 10 ns duration, pulses. Two-colour time-resolved spectra showed the formation of an excited species whose lifetime was shorter than the laser pulse widths used. The resonance Raman spectra of this species, identified as the lowest-lying "triplet" state, showed frequency shifts associated with porphyrin core expansion. The origins of the differences between the resonance Raman spectra of "triplet" Fe(TPP)Cl and triplet Zn(TPP) are discussed. © 1990.
