Abstract
The first picosecond and nanosecond time-resolved Raman spectra of photoexcited metalloporphyrins in the coordinating solvent piperidine are presented. Our data demonstrate that time-resolved resonance Raman spectra can be obtained from nickel octaethyl porphyrins and confirm the existence of photoinduced ligation changes in nickel octaethyl porphyrin species on a sub-nanosecond timescale. It is inferred from the power-dependent behavior of various porphyrin vibrational modes that multiple photochemical effects are contributing to the observed transient spectra.
