The intramolecular vibrational energy distribution of infrared multiphoton excited CF2Cl2 molecules is studied using time-resolved spontaneous Raman scattering. The time evolution of the signals from three vibrational modes is studied up to 600 ns after excitation and in the presence of N2 buffer gas. Following collisionless infrared multiphoton excitation a non-thermal distribution of vibrational energy is observed. The experimental result shows that equilibration of the intra-molecular vibrational energy distribution does not occur in this molecule up to at least 10,000 cm-1 of total internal vibrational energy.
