Measurement of Kinetic Rates for Carbon Monoxide Laser Systems.

Abstract

A continuous wave carbon monoxide laser is used to excite the vibrational mode of CO in gas mixtures flowing through an absorption cell. High steady-state excitation of the CO vibrational mode (0.3 eV/molecule) is achieved, while a translational-rotational temperature near 300 K is maintained by the steady flow of cold gas into the cell. These non-equilibrium conditions result in extreme vibration - vibration pumping, populating high-lying vibrational quantum levels (to V = 42) of CO. N2 can also be pumped by vibrational energy transfer from CO. Using this experimental technique, the vibration-translation (V-T) deactivation rates for high vibrational quantum levels of carbon monoxide have been measured for collisions carbon monoxide with argon at room temperature. The rates are quantum-state-resolved and have been measured for quantum level from V = 10 up V = 42.
