Abstract

The OH rotational distribution from O(1D) + H2O → 2OH is presented. The v' = 0 distribution corresponds to two Boltzmann distributions. ≈500 K (k = 1-6) and ≈2500 K (k ≥ 6). Rotational relaxation efficiencies for N2, He, O2 were ≤0.1, ≤0.1, ≤0.4. More limited data are presented for the v' = 1 and 2 levels.
