Determination of the rate constant of energy transfer from TF(ν=1) to CO2(0000) molecules in a chemical laser utilizing an NF3+T2 mixture

A determination was made of the rate of transfer of energy to the last pair of molecules TF–CO₂ in the XF–CO₂ series (X = H, D, T). The exchange of energy in this pair occurred under conditions of nearly complete resonance. The rate constant was found by analyzing the changes in the characteristics of an NF₃+T₂ laser on addition of CO₂ to the gas mixture. The rate constant representing the transfer of energy from TF(ν = 1) to CO₂(00⁰0) was K_t(TF–CO₂) ≥5×10^–22 cm³/sec, i.e., it was considerably greater than the rate constant K_t(DF–CO₂) = (5–8)×10^–12 cm³/sec.
