Show affiliationsA theoretical investigation of the DR of N2H+ to give N + NH has been undertaken because it is of interest for astrochemistry but also because the DR of N2H+ has been determined experimentally leading to controversial results. Using the same level of theory used to investigate the DR of N2H+ along the N2 + H reaction path, the present study shows that the lowest repulsive state of N2H leading to the NH and N fragments in their ground electronic states is likely going to cross the N2H+ ionic curve far above its v = 0 vibrational energy level. This study suggests that the DR of N2H+ to give N + NH should not be efficient in the low temperature of the interstellar clouds.
