The vibrational structure and dynamics of an excited electronic state of a polyatomic molecule, nickel octaethylporphyrine, have been measured at a picosecond time resolution for the first time. The experimental method was coherent anti-Stokes Raman spectroscopy. The decay time of the population of a lower-lying excited electronic state Td of this molecule in tetrahydrofuran has been determined from the kinetics of the coherent Raman spectra: 290 + 50 ps.
