Rate coefficient expressions for O+H,-+OH+H (5H) and O+D+OD+D (5D) over the temperature ranges 1600-2250 and 2370-3390 K, respectively, of &,=3.7x 10L4exp( -65 k.l/RT) and k5~=4.7~ lO'\*exp( -74 kJ/RT) cm3 mol-' s-i were derived from laser absorption spectroscopic measurements in shock-heated H2-02-
## Therateconstantexpression, k&.0x 1014exp( -95 kJ/RT) cm3 mol-' s-t, for H+O ,+O + OH was determined from cw laser absorption spectroscopic measurements of OH radical concentration growth rates in rich Hz-OZ-Ar mixtures heated to temperatures between 1900 and 2650 K in reflected shock waves.
The rate coefficient for the reaction (1) OH + OH --\* HzO + 0 has been determined in mixtures of nitric acid (HNO3) and argon in incident shock wave experiments. Quantitative OH time-histories were obtained by cw narrow-linewidth uv laser absorption of the Rl(5) line of the A2 x+ + X 2 ni (0,O) tra
