โœฆ Synopsis

Infrared double resonance and saturation techniques have both been used to measure the V-T relaxation of the 19 mode of CH3F in dilute solution in the cryogenic liquid hosts 02 and Ar. With the former technique, a relaxation time of 375 + 35 ns is found in liquid 02 while in liquid Ar the relaxation time is 1.30 2 0.15 c(s_ An induced v3 + 2~~ absorption is observed in the double resonance measurement; the measured anharmonicity is in good agreement with the gas phase literature value.
