Interpreting the fragmentation pattern of the mass spectrum of 2-methylpropene
[M]+ is the parent molecular ion peak (M) with an m/z of 56 corresponding to [C4H8]+, the original 2-methylpropene molecule minus an electron, [(CH3)2C=CH2]+.
The small M+1 peak at m/z ?, corresponds to an ionised 2-methylpropene molecule with one 13C atom in it i.e. an ionised 2-methylpropene molecule of formula [13C12C3H8]+
The most abundant ion of the molecule under mass spectrometry investigation (2-methylpropene) 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 2-methylpropene.
Unless otherwise indicated, assume the carbon atoms in 2-methylpropene are the 12C isotope.
Some of the possible positive ions, [molecular fragment]+, formed in the mass spectrometry of 2-methylpropene.
