The bimolecular rate constants for the reactions of ground state atomic nitrogen with hydrogen halides and deuterium iodide were measured by employing a pulse radiolysis-resonance absorption technique.As for the reactions of hydrogen iodide and deuterium iodide, the temperature dependence was also measured; it was found that the rate constants were well expressed by the following Arrhenius expressions: k(N+HI)=(3.6+/-0.6)E5 exp<-(1530+/-50)/T>; k(N+DI)=(1.0+/-0.4) exp<-(1460+/-130)/T>, in units of m³mol^-1s^-1.The preexponential factors for these reactions are much smaller than the semiempirically calculated ones.These small preexponential factors suggest that these reactions proceed non-adiabatically.The rate constants for hydrogen bromide and hydrogen chloride were found to be very small.
