Electron impact fragmentation patterns were obtained for perfluoroalkylether nitriles, C,F,O[CF(CF 3 )CFIO]ICF(CF 3 )CN (x = 1 and 2), perfluoroalkylether acyl halides, CSF,OCF(CF,)‐CF 2 OCF(CF 3 )COX (X = F and Cl), n‐perfluorooctanonitrile and n‐perfiuorooctanoyl chloride. The perfluoroalkyl and perfluoroalkylether nitriles afforded ions characteristic of the nitrile function. The major fragment from the acyl chlorides was the [COClJ]+ ion; the presence of chlorine was evidenced also by rearrangement ions of the general form [R f Cl] t. The perfluoroalkylether compounds appeared to undergo a typical fragmentation governed by the cleavage of the carbon‐oxygen bond.
