Methoxyethane
Interpreting the fragmentation pattern of the mass spectrum of methoxyethane [M]+ is the molecular ion peak (M) with an m/z of 60 corresponding to [C3H8O]+, the original methoxyethane molecule minus an electron, [CH3OCH2CH3]+. The small M+1 peak at m/z 61, corresponds to an ionised methoxyethane molecule with one 13C atom in it i.e. an ionised methoxyethane molecule of formula [13C12C2H8O]+
The most abundant ion of the molecule under mass spectrometry investigation (methoxyethane) is usually given an arbitrary abundance value of 100, called the base ion peak, and all other abundances ('intensities') are measured against it. Identifying the species giving the most prominent peaks (apart from M) in the fragmentation pattern of methoxyethane. Unless otherwise indicated, assume the carbon atoms in methoxyethane are the 12C isotope. Some of the possible positive ions, [molecular fragment]+, formed in the mass spectrometry of methoxyethane.
