Dissociative recombination of N2H+ ions with electrons in the temperature range of 80-350 K

Recombination of N₂H⁺ ions with electrons was studied using a stationary afterglow with a cavity ring-down spectrometer. We probed in situ the time evolutions of number densities of different rotational and vibrational states of recombining N₂H⁺ ions and determined the thermal recombination rate coefficients for N₂H⁺ in the temperature range of 80-350 K. The newly calculated vibrational transition moments of N₂H⁺ are used to explain the different values of recombination rate coefficients obtained in some of the previous studies. No statistically significant dependence of the measured recombination rate coefficient on the buffer gas number density was observed.

Compared with earlier years, the dissociative recombination of [Formula: see text] has not been very actively studied in recent years. New results from afterglow experiments are quoted and compared with results from ion storage rings and theory. New results for [Formula: see text] are discussed. This article also contains some historical remarks on hydrogen and its importance for the advancement of physics and chemistry. This article is part of a discussion meeting issue 'Advances in hydrogen molecular ions: H₃⁺, H₅⁺ and beyond'.
