WebAug 15, 2024 · The molecular ions are energetically unstable, and some of them will break up into smaller pieces. The simplest case is that a molecular ion breaks into two parts - one of which is another positive ion, and the other is an uncharged free radical. (1) M ⋅ + → X + + Y ⋅ The uncharged free radical won't produce a line on the mass spectrum. WebAug 15, 2024 · Alkane Molecular ion peaks are present, possibly with low intensity. The fragmentation pattern contains clusters of peaks 14 mass units apart (which represent loss of (CH2)nCH3). Hexane (C6H14) with MW = 86.18 Amide Primary amides show a base peak due to the McLafferty rearrangement. 3-Methylbutyramide (C 5 H 11 NO) with MW …
