SiF4 and SF6 was in accord with previously reported rate data for the removal of Si(3 3PJ), Si(3 1D2) and Si(3 1S0). The decay components of the SiF(X2Πr) derived from the profiles yielded the following absolute second-order rate constants for reaction with RF: [graphic omitted] F-atom abstraction being highly exothermic in all cases and demonstrating similar reactivity to atomic silicon itself.
