Abstract
A detailed neutral kinetic scheme for the production and quenching of ArF* and Ar2F* is provided from time‐resolved and time‐integrated spectra for proton‐excited Ar–F2 mixtures at various partial pressures. The mechanism for the production of Ar2F* is concluded mainly from the three‐body quenching of ArF* by argon. It is also found that the efficiency to produce ArF* by Ar2* (1u) with F2 is comparable to Ar(3P2) colliding with F2. The two‐body quenching rate constants of ArF* and Ar2F* by F2, the three‐body quenching rate constant of ArF* by Ar, and the radiative lifetime of Ar2F* are also obtained. The mechanism of ion–ion recombination to produce ArF* is briefly discussed.
