• 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: <I>k</I>(N+HI)=(3.6±0.6)×10<SUP>5</SUP> exp[−(1530±50)⁄<I>T</I>]; <I>k</I>(N+DI)=(1.0±0.4)×10<SUP>5</SUP> exp[−(1460±130)⁄<I>T</I>], in units of m<SUP>3</SUP> mol<SUP>−1</SUP> s<SUP>−1</SUP>. 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.
