Krypton chloride and krypton fluoride thermochemistry and formation and relaxation kinetics in argon, nitrogen, and tetrafluoromethane buffer gas

摘要: Krypton chloride and krypton fluoride molecules were formed by the Kr({sup 3}P{sub 1}) sensitization reaction with Cl{sub 2} or F{sub in variable pressures (up to 5 atm) of Ar, N{sub 2}, CF{sub 4} buffer gases at 300 230 K. Less extensive experiments also done He Ne. The high-pressure (equilibrium) KrF(C)/KrF(B) KrCl(C)/KrCl(B) ratios observed order assign energy separation C B states. KrF(B,C) + 2Ar rate constant for ArKrF{sup *} formation was assigned as (8 {plus minus} 3) {times} 10{sup {minus}33} cm{sup 6} molecule{sup {minus}2} s{sup {minus}1} K; a slight larger value estimated ArKrCl{sup *}.
