Unravelling the reactivity of antisymmetric stretch-excited CH4 with Cl by-product pair-correlation measurements

Abstract

The vibrational branching ratio [CH₃(v = 0) + HCl(v′ = 1)]/[CH₃(v = 0) + HCl(v′ = 0)] of two correlated product pairs from the title reaction shows a dramatic E_c-dependence, in sharp contrast to the previously observed behavior in Cl + CHD₃(v₁ = 1), while the vibrational enhancement factors in reactivity of the two reactions are remarkably similar.
