TL;DR: In this paper, weak collision broadening factors were derived and represented empirically for thermal unimolecular reactions in the fall-off range, which are useful for data representation and modeling of complex reaction system which involve isomerization, dissociation and recombination reactions.
Abstract: The master equation of thermal unimolecular reactions in the fall-off range has been solved for a number of representative molecular systems. Weak collision broadening factors F**W**C(k// /k// infinity ) are derived and represented empirically. Weak collision efficiencies beta //c for the low pressure range are calculated for very high temperatures. Combined with earlier representations (part I) of strong collision broadening factors F**S**C(k//0/k// infinity ), compact empirical expressions for the rate coefficient in the full fall-off range are proposed. These expressions are useful for data representation and modeling of complex reaction system which involve isomerization, dissociation and recombination reactions.
