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

both the first and second field-free regions, and assignments were confirmed by high-resolution accurate mass measurement. The main fragmentation reactions occurring are shown in Scheme 1. The mass-to-charge ratios and relative abundances of characteristic ions are listed in Table 1, and the complet
The mass spectra of several alkyl phenyI tellurides, C6H5TeR (R = CH,, CD,, CaH5, n-CsH,, i-C,H, and n-C4HB) have been studied with special emphasis on the fragmentation patterns involving cleavage of the alkyl and aryl tellurium-carbon bonds. Each compound exhibited intense parent ions. The rearran
