Interpreting the fragmentation pattern of the mass spectrum of 1,1,1-trichloroethane
There is no [M]+ the molecular ion peak (M) with an m/z of 132, 134, 136 or 138 corresponding to [C2H3Cl3]+, the original 1,1,1-trichloroethane molecule minus an electron, depending on the chlorine isotopic composition of the 1,1,1-trichloromethane molecule Cl3CCH3.
The most abundant ion of the molecule under mass spectrometry investigation (1,1,1-trichloroethane) 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 1,1,1-trichloroethane.
Unless otherwise indicated, assume the carbon atoms in 1,1,1-trichloroethane are the 12C isotope, but the chlorine atoms maybe 35Cl or 37Cl and this makes the mass spectrum even more complex to interpret.
Some of the possible positive ions, [molecular fragment]+, formed in the mass spectrometry of 1,1,1-trichloroethane.
