Peaks of characteristic ions in the electron ionization mass spectra of substituted β-nitrostyrenes are identified, and mechanisms of their formation are determined
General fragmentation pathways for nitro-substituted di(aryl)isoxazolines under electron ionization are determined. Ions useful for differentiation of positional and stereo-isomers are established.

General and specific fragmentation pathways of trifluoroacetyl and heptafluorobutyryl derivatives of primary and secondary amines under electron ionization are determined. The derivatives are obtained as a result of on-column acylation.
