The structures of some new carboxamide, thiocarboxamide, nicotinoyl and isonicotinoyl pyrazoline derivatives have been related to their mass spectral data. The ions produced under electron impact showed both the characteristic pyrazoline ion and unusual azete fragmentation patterns. These results su

✦ Synopsis
A mass spectrometric study of several para-substituted benzylidenecyanoacetamides was performed; thus, electron impact, chemical ionization and fast atom bombardment mass spectrometric studies for each molecule were acquired and then compared in order to establish a general fragmentation pattern. In (establish) particular the electron impact pathways were investigated and confirmed by using constant B/E linked scans and high resolution data.

A series of cyclic esters, which are optically active as a consequence of their helical structures, were synthesized to investigate the relationships between their structures and their optical activities. This paper reports the electron impact fragmentation mechanisms of these six cyclic esters. Acc
The electron ionization mass spectrometric behaviour of a series of dimethylindium derivatives with piperidine, pyrrolidine, azetidine and methylaziridine were investigated. These data have been compared with data from mass-analysed ion kinetic energy spectrometry. Fragmentation patterns of the comp
