    Raman spectroscopy of infrared multiphoton excited molecules, at XIVth Int. Quantum Electronics Conf. (San Francisco, CA), Wednesday, January 1, 1986
    Anti-Stokes signals from various modes of isolated, infrared multiphoton excited SF6 and C2H4F2 molecules are measured as a function of pressure, infrared fluence and wavelength. This allows to verify whether intramolecular equilibrium of vibrational energy is established after infrared multiphoton excitation in isolated molecules.
    The interaction of infrared radiation with isolated molecules: intramolecular nonequilibrium, at Lasers ¹86 Conference (Orlando, FL), Saturday, November 1, 1986
    Anti-Stokes signals from various modes of isolated, infrared multiple photon excited molecules are measured to determine the intramolecular distribution of vibrational energy. This paper presents results for CF2HCl, CF2Cl2, SF6 and 1,1-C2H4F2. All but CF2HCl exhibit collisionless changes in Raman spectrum after infrared multiphoton excitation. This shows that the excitation modifies the population of these modes. Even though the symmetric SF6 molecule reaches an intramolecular equilibrium within the 20 ns time resolution of the experiment, the other molecules exhibit a distinct nonequilibrium...
