Abstract
The formation of a hot photoproduct of nickel octaethylporphyrin (NiOEP) upon ππ*
excitation and its subsequent vibrational energy relaxation were monitored by
picosecond time-resolved resonance Raman spectroscopy. Resonance Raman bands
due to the photoproduct instantaneously appeared upon the photoexcitation. Their
intensities decayed with a time constant of 330±20ps, which indicates electronic
relaxation form the (d, d) excited state (
