Abstract : The temperature dependence of the collisional deactivation of O(singlet S) has been investigated in the range 153-500K. O(singlet S) was produced in a pulsed mode by flash photolysing CO2 in the vacuum ultraviolet and detected by the forbidden singlet S to singlet D emission at 5577 A as a function of time after the production pulse. Rate constants were derived from the decay rate of the Osinglet S) concentration. The temperature dependence was found to follow the Arrhenius equation. (Modified author abstract)
