Notizen:
The mass spectra obtained from ions having excess kinetic energy (named the excess kinetic energy mass spectra) formed by electron impact of several aliphatic amines have been studied. Comparison with the excess kinetic energy mass spectra of the analogous alcohols shows many similarities. For example, the intensity of the [CH2OH]+ ion of an aminoalcohol is about the same as the intensity of the [CH2NH2]+ ion. The excess kinetic energy mass spectra give useful information about the presence or absence of various functional groups, such as CH2NH2, CH2OH, CH3CHNH2 and alkyl groups, and also about rearrangements. The fragmentation mechanisms are straightforward and applicable to a variety of classes of compounds. The molecular weight dependence of excess kinetic energy mass spectra is described.
