Rationalizing the S(1D) + H2 → SH(X2Π) + H reaction dynamics through a semi-classical capture model

The dynamics of the title process is investigated using a semi-classical capture model. Such a model leads to predictions in nice agreement with recent state-of-the-art exact quantum scattering calculations and experiments. The role of reactive resonances, which are thought to play a role at low collision energy, is highlighted. In line with Professor Rayez’s carrier achievements, this work illustrates how simple models may help rationalizing the dynamics of elementary reactions.
