โœฆ Synopsis


  1. 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.

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
