An experimental survey of the reactions of NHn+ ions n=0 to 4) with several diatomic and polyatomic molecules at 300 K

Article abstract of DOI:10.1063/1.438893

A study has been made of the binary reactions at 300 K in a SIFT apparatus of the ions N⁺, NH⁺, NH2⁺, NH3⁺, and NH4⁺ with CH3NH2, NO, NH3, H2S, CH3OH, H2CO, COS, O2, H2O, CH4, CO2, CO, H2, and N2.The N⁺, NH⁺, and NH2⁺ reactions are generally fast, their rate coeeficients being close to the collisional limit, and multiple product channels result, especially for reactions with the polyatomic molecules.Several reaction mechanisms are apparent, including charge transfer, proton transfer, and H-atom abstraction, although it is argued that many of the reactions preceed via a short-lived, ion-molecule complex which separates along the observed reaction channels.The NH3⁺ ions are seen to be generally less reactive than the lesser hydrogenated ions, the product of most of the reactions being NH4⁺ ions which do not undergo binary reactions with any of the molecules (except CH3NH2) but rather undergo ternary association reactions with a few of them.A few measurements were mede using the deuterated analogs ND⁺, ND2⁺, ND3⁺, and ND4⁺ in order to shed further light on some of the reaction mechanisms.
