The positive ion chemical ionization (CI (isobutane)), negative ion chemical ionization (NICI) electron attachment (CH,,, He) and NICI (OH-) spectra of the title compounds have been studied in detail with the aid of deuterium-labelled derivatives. me obtained results show that under CI conditions th
The N, negative ion chemical ionization (NICI) mass spectra of aniline, aminonaphthalenes, aminobiphenyls and aminoanthracenes show an unexpected addition appearing at [ M + 11 1 -'. This addition is also observed in the N, positive chemical ionization (PCI) mass spectra. An ion at IM -151-is found
