Energy dependence of the reaction of CH+2 with HCl

Abstract
The energy dependence of the reaction of CH+2 with HCl has been investigated using a selected ion flow drift tube (SIFDT) in the center‐of‐mass kinetic energy (KEc.m.) range from 0.04–2 eV. The reaction rate coefficient is fast at near thermal energies (k∼1.5×10−9 cm3 s−1) but decreases dramatically with increasing KEc.m. to k−10 cm3 s−1 at 2 eV, which is quite uncommon for a thermally fast ion–molecule reaction.
