Paper Abstract

Rate constants for the removal of O2 b1+g by collisions with O2, N2, CO2 and H2O have been determined at temperature 297 K. O2(b1 +g) was excited by pulses from a tunable dye laser, and the deactivation kinetics were followed by observing the temporal behavior of the b1+g - X3-g fluorescence. The removal rate constants for CO2, N2 and H2O were not strongly dependent on temperature, and could be represented by the expressions kCO2=(1.8±0.05)×10-16; kN2=(2.2 ± 0.2)×10-15, and kH2O=(6.12±0.67)×10-12 cm3 molecule-1 s-1. Rate constant for O2(b1+ ) removal by O2(X), being orders of magnitude lower, represented by the fitted expression kO2=(3.67 ± 0.06)×10-17 cm3 molecule-1 s-1. All of the rate constants measured at room temperature were found to be in good agreement with previously reported values.
