The formation of nitrogen hydrides in the interstellar medium is initiated by the nearly thermoneutral reaction of N ^+ + H _2 → NH ^+ + H. Here, we experimentally determine the enthalpy of this reaction using the principle of detailed balance from

This paper presents the results of an experimental study of the reaction of OH ^− anions with HD molecules leading to the formation of OD ^− anions. The study’s main goal was to obtain the temperature dependence of the reaction rate coefficient

This work is motivated by many observations of nitrogen hydrides including their isotopologues in the interstellar space. We studied the formation of NH+ and ND+ ions in the nearly thermoneutral hydrogen abstraction reactions of N+ ions with H2, HD,

We present studies on the thermalisation of H3+ ions in a cold He/Ar/H2 plasma at temperatures 30–70 K. We show that we are able to generate a rotationally thermalised H3+ ensemble with a population of rotational and nuclear spin states correspondi

We studied the reaction of doubly charged carbon C2+ (C iii) with molecular hydrogen, a possible source of the high, unexplained abundances of interstellar CH+. The experiment was carried out using the cryogenic linear 22-pole radio frequency ion tra

The reactions of the O+ ions in the 4S electronic ground state with D2 and HD were studied in a cryogenic 22-pole radio-frequency ion trap in the temperature range of 15 K–300 K. The obtained reaction rate coefficients for both reactions are, consi

Synopsis The reaction of dication C++ with H2 was studied at temperature 20 K using a linear 22-pole radiofrequency ion trap. The overall reaction rate coefficient was measured as 1.4 ± 0.3 × 10−10 cm3 s−1. The upper limit for formation of CH+
