Abstract
A parametric oscillator has been employed to pump ground‐state carbon monoxide molecules in a gas‐phase sample directly to the second vibrational level. The decay of the population of this level via vibration‐vibration (V‐V) energy transfer with ground‐state molecules, CO(v = 2) + CO(v = 0) → CO(v = 1) + CO(v = 1), has been monitored as a function of pressure, resulting in the first experimental determination of the rate constant for this process, 6.2 × 104 sec−1 Torr−1 at 295 °K.Keywords
