Interpreting the fragmentation pattern of the mass spectrum of ethylamine
[M]+ is the molecular ion peak with an m/z of 45 corresponding to [C2H7N]+, the original ethylamine molecule minus an electron, [CH3CH2NH2]+.
The tiny M+1 peak at m/z 46, corresponds to an ionised ethylamine molecule with one 13C atom in it i.e. an ionised ethylamine molecule of formula [13C12CH7N]+
The most abundant ion of the molecule under mass spectrometry investigation (ethylamine) 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 ethylamine.
Unless otherwise indicated, assume the carbon atoms in ethylamine are the 12C isotope.
Some of the possible positive ions, [molecular fragment]+, formed in the mass spectrometry of ethylamine.
