The experiments were complemented by calculations of stationary points on the triplet hypersurface of the system. The scattering data showed that the reaction proceeds by the formation of two intermediate complexes having different lifetimes: it long-lived statistical intermediate and short-lived complex (mean lifetime about one period of an average rotation) with more energy in translation than the statistical complex. Comparison with theoretical Calculations suggests that the long-lived complex leads the CDND+ isomer of the product ion, whereas the short-lived complex leads prevailingly to the CD2N+ isomer. The product DCN+ results from further decomposition of the primary product D2CN+, whereas CD3+ is formed both by a hydride-ion transfer and it long-lived complex decomposition.
