ANCA MOANTA CHARACTERISTIC FRAGMENTATION PATTERNS OF SOME 4-(PHENYLAZO)PHENOLS OBTAINED BY ELECTRON IMPACT MASS SPECTROMETRY
The mass spectra of fourteen substituted 4-(phenylazo)phenols have been recorded and compared. The most intense peaks have been used to characterize these spectra. The molecular ions are observed as highest intensity peaks. The influence of the substituents on the fragmentation is discussed.
