Dynamics of OH Production in the Reaction of O(3PJ) with SiH4

Article abstract of DOI:10.1021/j100312a033

Laser-induced fluorescence detection of the OH product following the reaction O(³P_J)+SiH4 --> OH(X²Π)+SiH3 reveals a strong vibrational population inversion, P(1)/P(0) = 3.4 +/-0.4.The rotational distribution of the major product in ν =1 is thermal with T_rot=600 +/-20 K.The product distribution of OH in ν =0 cannot be simply characterized in terms of a temperature, nor does the population ratio for the Λ doublet components provide unambiguous evidence concerning the production mechanism, but it clearly differs from that responsible for production of the vibrationally excited products.
