Abstract
The rates for deactivation of singlet oxygen, O2(b1(Sigma) g+), upon collision with pyrex, Teflon, aluminum, copper, and nickel surfaces have been determined in a steady-state flow tube reactor. Numerical and approximate analytic solutions of the radial diffusion equation with coaxial cylindrical boundary conditions are presented to obtain wall deactivation probabilities from observed first order decay rates. The probability for deactivation at nickel surfaces is large, (gamma) equals 0.026. However, it is unlikely that surface deactivation of O2(b1(Sigma) g+) in Chemical Oxygen-Iodine Lasers has any significant effect on laser performance.
