Abstract: Freon 113 molecules are superexited in multifrequency intense IR laser fields composed of 9P(24), 9P(22), 9P(20), 9P(18) lines of TEA CO2 laser, reaching very high exited states. It can be seen from the decomposition curve that a "siphonage effect" exists obviously in the V-V energy transfer between CF2C1·CFC12 and CF3·CCl3 molecules. From the main products C2F6, C2Cl6, C2F4 and C2F2C12, it is shown that the C-C bonds having higher energy in CF2Cl·CFCl2 and CF3·CCl3 were mostly broken, but only a few C-Cl bands having lowest energy ruptured. We propose a dissociation mechanism of Freon 113 molecule in multifrequency intense IR fields, and indicate that intramolecular V-V energy transfer is not randomized.
