[en] The infrared chemiluminescence method has been used to study the product vibrational and rotational distributions arising from the reaction F + H₂ → HF + H with an uncollimated beam of normal hydrogen coming from an inlet at 77 K and at 290 K and with para hydrogen at the same two inlet temperatures. The variation of the spin-isomer and temperature for the H₂ afforded a variety of reagent rotational distributions. The corresponding variation in product vibrational distribution was analyzed to yield detailed rate constants, k(γ'/J), from specified states of reagent rotation J=0,1,2 into specified product vibrational levels, γ'. The results can be summarized by saying that there is a small but significant decrease in the fraction of the total energy entering product vibration, < fsub(V)'>, in going from J=0 to J=1, and then an increase in this fraction as J is further increased from J=1 to J=2. The product rotational excitation is invariant with J, within experimental error, over this range of J. These findings are discussed in terms of existing classical trajectory studies. (Auth.)
