Description
Methanimine (NHCH2) is the simplest imine, and is of astrophysical interest in interstellar dust clouds. In this study, NHCH2+ was generated by x-ray irradiation of a mixture of dinitrogen and methane, and their various isotopologues. Neutral species were trapped in an inert neon gas matrix by depositing the gas mixture onto a copper surface cooled to 4 K by liquid helium. The resulting matrix was then x-irradiated for varying lengths of time and power to optimize generation conditions. Electron spin resonance spectra of the irradiated matrix were recorded to give insight into the electronic structure and behavior of this radical cation in the neon matrix.
