Vibrational relaxation of highly excited diatomics. IV. HF(v=1-7) + CO2, N2O, and HF

Article abstract of DOI:10.1063/1.446248

Vibrational relaxation rate constants are measured for HF(υ = 1-4) with Q=CO2, N2O, and HF by the fast flow infrared chemiluminescence technique using four HF(υ) generating reactions whose initial vibrational distributions are found be be unrelaxed.The data combined with earlier results for υ=5,6, and 7 to provide information on υ dependence and quenching mechanism.The rate constants, k^Q_υυ-1 range from 1.2*10^-12 to 4.5*10^-10 cm³ s^-1 and increase with power law exponents n of 2.7 to 3.0 in k<*>υⁿ for all three quenchers.The relaxation is principally V-V for CO2 and N2O, but mainly V-R,T for HF, at least for the higher υ levels.The relaxation rate constants are compared with theoretical estimates and form a valuable data base for future theoretical work.
