Some ion-molecule reactions of hydrogen cyanide

Abstract

Rate coefficients for the reactions of several positive ions with HCN in the gas phase have been measured by the flowing afterglow technique. The reactions are all of the form

                         X⁺+HCN → products

. where X⁺ and the corresponding rate coefficient, in units of cm³ molecule^-1 s^-1, are: X⁺ = HCN⁺ (k 9.8×10^-10); C₂N⁺ (k 3.1×10^-10); CN⁺ (k 2.8×10^-9 CH⁺ (k 3.2×10^-9); H₃O⁺ (k 4.5×10^-9 and HCO⁺ (k 3.9×10^-9).
