Stationary afterglow with Cavity Ring Down Spectrometer was utilized to probe the number densities of H3+, H2D+, HD2+ and D3+ ions in discharge and afterglow plasma. The recombination rate coefficients for recombination of H2D+ and HD2+ ions with electrons were obtained from the time decays of overall ion number density at different fractions of [H2]/[D2].
