The [CH5NO]+ ˙ potential energy surface: Distonic ions, lon‐dipole complexes and hydrogen‐bridged radical cations

Abstract By combining results from a variety of mass spectrometric techniques (metastable ion, collisional activation, collision‐induced dissociative ionization, neutralization‐reionization spectrometry, 2 H, 13 C and 18 O isotopic labelling and appearance energy measurements) and high‐level ab initio molecular orbital calculations, the potential energy surface of the [CH 5 NO] + ˙ system has been explored. The calculations show that at least …
