Inter- and Intramolecular Vibrational Distribution in IR Multiple Photon Excitation: CF2Cl2 Molecule
Vibrational energy distribution of IR MP-excited CF2Cl2 is studied when pumping molecules through ν1 and ν8 modes. In both cases the intermolecular distribution is found to be in a state of nonequilibrium consisting of ensembles of “hot” and “cold” molecules. The structure of the “cold” ensemble is different when ν1 and ν8 modes are pumped. Statistical intramolecular energy distribution caused by stochastization of vibrational motion is found for “hot” molecules. The estimated value of stochastization onset energy equals Eth ≤ 7800 cm−1.
