“…Since higher vibrational quanta exchange is involved in process ( 5 ) , thus the probability of process (5) will be smaller than that of process (7) by, nearly, one order of magnitude, i.e., P6= 10-2, k4= Z4P4; k,=Z,P, 2ssUF6( v3) +238UFg+236UFe + 238UFa(vVS)…”

The photochemical vibrational reaction of UF6+HCl was investigated by exciting the ternary overtone of 3V3 of UF6 in an intracavity CO laser system. It was found that the rate of the laser‐driven reaction was much greater than that of the thermal reaction and this photochemical process had an isotopic selectivity. The uranium isotope enrichment factors measured in experiments were around 1,007 in a single step.

Experiments on the effect of selective vibrational, translational and orientations excitation of reactants in bimolecular reactions can give important insights into the microscopic dynamics of elementary chemical reactions. The information obtained in such experiments can be compared with the results of theoretical calculations of the reaction dynamics based on ab initio potential energy surfaces and is also of basic interest to improve the kinetic data used in detailed chemical kinetic modelling. Rotational and vibrational energy transfer between H2 and H0 has been studied directly using Raman excitation combined with time resolved CARS spectroscopy. The competition between reactive and inelastic channels was investigated for reactions of atoms with vibrationally excited H2 and HCI molecules. Selective vibrational excitation was achieved by using infrared laser or Raman-pumping. The reaction products were detected by time resolved atomic line resonance absorption mass-spectrometry and CARS-spectroscopy. Insome cases information on the contributions of adiabatic and non-adiabatic reactive pathways could be obtained. The reaction H + O2-OH + O has been studied using translationally hot H atoms at various energies. Absolute total reactive cross-sections, nascent rotational state distributions and information on the distribution of orientations of the OH angular momentum vector using polarized dissociation and analysis laser sources have been obtained.
