Coherent anti-Stokes Raman spectroscopy has been used to study collision processes and to determine the rate of transfer of vibrational energy in SF6 and SiF4 molecules excited by the IR field from a C02 laser. The mechanism for the fast intermode energy exchange, which results from the effect of highly excited states, is discussed.
