Abstrakt: Recombination of N 2 H + 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 N 2 H + ions and determined the thermal recombination rate coefficients for N 2 H + in the temperature range of 80-350 K. The newly calculated vibrational transition moments of N 2 H + 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.
