Vibrational energy relaxation of CH 3F dissolved in liquid O 2 and Ar
Abstract
Infrared double resonance and saturation techniques have both been used to measure the VT relaxation of the ν 3 mode of CH 3F in dilute solution in the cryogenic liquid hosts O 2 and Ar. With the former technique, a relaxation time of 375 ± 35 ns is found in liquid O 2 while in liquid Ar the relaxation time is 1.30 ± 0.15 μs. An induced ν 3 → 2ν 3 absorption is observed in the double resonance measurement; the measured anharmonicity is in good agreement with the gas phase literature value.
