✦ Synopsis

The nascent rotational and fine-structure state distributions in OH (o = 0) produced in the endothermic reaction H + CO2 OH + CO have been measured with hot hydrogen atoms from the photodissociation of HBr at 193 nm. Considerable OH rotational excitation broadly peaked at around K = 11 is observed. The OH spin doublets are produced statistically (_+10%).

The partitioning between the h doublets is non-statistical with a strong preference for the 7r + component (o(n+)/a(n -) = 3.0 _+ 1.0), consistent with a planar HOCO intermediate whose OC-OH bond breaks in that plane.

The kinetics of the reactions of H atoms with H2S and with COS were measured at 298' K in a flow system using mass-spectrometric detection. The rate constants were found to be 3.8 X 10-13 and 2.2 X lo-'\* cm3 part-' sec-l, respectively, with an estimated accuracy of 25y0. At high flow rates of HZS,

## Abstract The reaction Cl + H~2~CO → HCl + HCO has been studied at 295 K. Chlorine atoms were produced via the infrared laser induced dissociation of CCl~3~F, using a pulsed CO~2~ TEA laser. Using HCl infrared chemiluminescence as the diagnostic, we find the rate constant to be 7.4 ± 0.7 × 10^−11

In this work we studied the collinear F(\*P,$ + Hz system in a strong CO2 laser field. It was found that the tiajecror) surface hopping method (TSHM) yields entirely different results than the exact quantum-mechanical treatment. A curvecrossing model was devised to esplain the discrepancy.
