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

SymPy is an open source computer algebra system written in pure Python. It is built with a focus on extensibility and ease of use, through both interactive and programmatic applications. These characteristics have led SymPy to become a popular symbol

We have studied the three-body complex formation rate of the hydroxyl anion with molecular hydrogen at low temperatures. The formed cluster is found to quickly undergo internal proton transfer to a hydrogen anion–water complex. This is probed by ph

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
