Formation of interstellar SH${}^{+}$ from vibrationally excited H${}_2$: Quantum study of S${}^{+}$ + H${}_2$ $\rightleftarrows$ SH${}^{+}$ + H reactions and inelastic collisions

Alexandre Zanchet, Francois Lique, Octavio Roncero +2

The rate constants for the formation, destruction, and collisional excitation of SH${}^{+}$ are calculated from quantum mechanical approaches using two new SH${}_2^{+}$ potential energy su…
