Is ion on spectrum.

EI mass spectra, in most of cases, contain intense fragment ion peaks and much less intense molecular ion peak. When the molecular ion peak is not observed in the mass spectrum, chemical ionization can be used in order to get molecular ion information. One helpful rule for determining whether an ion is a molecular ion is the Nitrogen Rule.Even electron ions have all paired electrons. An example of this was shown in the mass spectrum of acetone where the molecular ion, CH 3 –CO–CH 3 +•, fragments to form CO–CH 3 + - an even electron ion observed at an 43 m/z.

The mass spectrum will therefore have a line corresponding to the molecular ion [13 CH 4] + as well as [12 CH 4] +. The line at m/z = 17 will be much smaller than the line at m/z = 16 because the carbon-13 isotope is much less common.The ion energy spectra in the simulations including ionization are significantly shaped comparing with those from the simulations using a pre-ionized plasma.
