A first study of the fragmentation of aromatic N-oxides upon electron impact was made by Bryce and Maxwell in 1965 (1) and they reported that the presence of M-16 peaks was diagnostic for these N-oxides. However, Grigg and Ode11 (2) observed the decrease of the M-16 peak and the appearance of an M-1

โฆ Synopsis
- Neopentyl phenyl eulfide givee no M-33 peak (7). vherrae the peek is observed in the epectra of phenyl mercaptan (lO$), benzyl mercaptan (lo&), vinyl methyl eulfide (95%) (2), l thynyl methyl eulfide (lO$) (2). and come of dieulfidoe (5). 7. M. Fieher end C. Djeraeei. E. & 750 (1966). -8. Deuterium isotope effect is not taken into account. 9. The mace spectra were taken with a HITACHI Maee Spectrometer Model RM' 5D , using an all-glass inlet eystem. The ioniring potential was kept at 70 e.V. and the ionizing current at 80 P.

Electron impact (EI) using ionizing electrons of different kinetic energies, ammonia and methane positive chemical ionization (PCI) and plasma desorption (PD) mass spectrometry were used for the analysis of aryl pesticides of the carbamate and phenylurea families. Under PD conditions, competitive fo
