A Statistical Model for Hydrogen Halide Product Distributions Using Information Theory

Abstract

Chemical laser modeling is dependent on the reaction rate coefficients available from both experiment and theory. A statistical model has been developed to correlate the relative rate coefficients for the laser pumping reactions: (I) F + H2 yields HF(v,J) + H, (II) F + D2 yields DF(v,J) + D, (III) H + F2 yields HF(v,J) + F, (IV) D+ F2 yields DF(v,J) + F, (V) H + CL2 yields HCL(v,J) + CL, (VI) D + CL2 yields DCL(v,J) + CL, (VII) H + Br2 yields HBr(v,J) + Br, and (VIII) D + Br2 yields DBr(v,J) + Br. The detailed product distributions for Reactions (IV) and (VIII) are generated by the model. The model uses surprisal analysis to relate the product rotational distributions for each reaction by considering each vibrational level separately. The model results coupled with the observed vibrational distributions favorably reproduce the rotational distributions for Reactions (III) and (VII). Assuming an isotopic independence for some parameters between Reactions (III) and (IV) and between (VII) and (VIII), the model can generate the full vibrotational distributions for (IV) and (VIII) from a small set of input parameters.
