Vibrational energy transfer in molecular oxygen collisions

Rate coefficients for the relaxation of vibrational excited oxygen molecules, including both vibration-to-vibration (V–V) and vibration-to-translation (V–T) energy exchange, have been calculated using a semiclassical method and a new potential energy surface for a large interval of initial vibrational quantum numbers (1⩽v⩽29) in the temperature range between 50 and 1000 K.
