Measurements of rate coefficients of CN+, HCN+, and HNC+ collisions with H2 at cryogenic temperatures

Popis výsledku v původním jazyce

The experimental determination of the reaction rate coefficients for production and destruction of HCN+ and HNC+ in collision with H-2 is presented. A variable-temperature, 22-pole radio frequency ion trap was used to study the reactions in the temperature range 17-250 K. The obtained rate coefficients for the reaction of CN+ and HCN+ with H-2 are close to the collisional (Langevin) value, whereas that for the reaction of HNC+ with H-2 is quickly decreasing with increasing temperature. The product branching ratios for the reaction of CN+ with H-2 are also reported and show a notable decrease of the HNC+ product with respect to the HCN+ product with increasing temperature. These measurements have consequences for current astrochemical models of cyanide chemistry, in particular, for the HCNH+ cation.
