Nuclear-Spin Effects with Ammonia Chemistry in Ion Trap Experiment
Original language description
Our research focuses on the fundamental processes of ammonia chemistry in space, particularly on the effects of nuclear spin states. Using a 22-pole cryogenic ion trap, we investigated the reactions of NH2+ and NH3+ with H2, measuring the reaction rate coefficients at 270 K. We determined the rate coefficients to be (3.5 +- 07) x 10-10 cm3s-1for the reaction NH2+ + H2 -> NH3+ + H, and (5.7 +/- 1.2) x 10e-13 cm3s-1 for the reaction NH3+ + H2 -> NH4+ + H. Our findings indicate that the nuclear spin state of H2 does not significantly influence these reaction rates at this temperature.
