Electron impact m a s spectra of 65 pyrrolidine-N-oxyl derivatives have been assigned on a 'peak-to-subgraph' basis. On average, 50% of the total ion current is represented by structurally significant fragments associated with the nitroxide group. Secondary fragmentation is, as a rule, of a minor im
The mass spectrometrical fragmentation patterns of the 4.4-dimethyloxazoline derivatives (DMOX) of the studied 0x0 fatty acids are easily to understand. The 0x0 group positions can be assigned unequivocally, The spectra are similar to those of the corresponding pyrrolidide derivatives. Since DMOX de
