Abstract:

The temperature dependence of the collisional deactivation of Osinglet S has been investigated in the range 153-500K. Osinglet 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
