The nascent state distributions of OH produced in the reaction H+H20+0H+H2
were probed by fast atom-laser-induced fluorescence experiments. Translationally hot H atoms were formed by photolysis of HI at 250 and 270 nm leading to H+HrO c.m. collision energies E of 176 and 143 kJ/mol. With a calibration method using HNOs photolysis as OH-precursor absolute reaction cross sections of 0.27kO.12 A2 (E= 176 kJ/mol) and 0.17kO.07 A* (E= 143 kJ/mol) were measured. The OH rotational and vibrational state distributions as well as reaction cross sections are compared with previous theoretical results based on quasiclassical trajectory calculations on an ab initio potential energy surface.

Photolysis of HCI with an ArF excimer laser at 193 nm yields H atoms with well-defined high translational energy ( I .86 eV) which react with CO2 to form OH and CO. The product OH radicals are detected by laser-induced fluorescence (LIF). From LIF spectra the nascent OH vibrational, rotational and t
## Using translationally excited H atoms generated by laser photolysis of H2S at 193 nm, the reaction dynamics of H + H,O+OH + H2 and H + COIdOH + CO was investigated at collision energies of 2.2 and 2.3 eV, respectively. Nascent OH rotational and vibrational quantum-state distributions and OH pro
