Electron impact ionization of acrylonitrile

An electron impact (EI) ion source and a double focusing sector field mass spectrometer were used to investigate ionization processes of acrylonitrile C3H3N. The ionization and appearance energies for observed singly CxHyNz+ (x = 1-3; y = 0, 1, 3; z = 0, 1) and doubly C3H3N2+ and C3HN2+ charged ions were determined by using the non-linear least-square fitting procedure to the raising set of the data points. In the case of ions: C2HN+/C3H3+, C2N+/C3H2+, C3H+, C3+, CH2N+, CHN+/C2H3+, C2H+, C2+, H2N+, HN+/CH3+, CH2+/N+, CH+, C+, C3H3N2+ and C3HN2+ these energies were obtained for the first time.
