Abstract The 70 eV electron impact mass spectrometric behaviour of some fluorinated alcohols, i.e. 2‐fluoroethanol, 2,2,2,‐trifluoroethanol, 2,2,3,3‐tetrafluoropropan‐1‐ol and 1.3‐difluoropropan‐2‐ol, was studied in detail by means of mass‐analysed ion kinetic energy Spectrometry, deuterium‐labelling experiments and comparison with unfluorinated analogues. Composite metastable peaks related to HF losses were rationalized by invoking the presence of two concurrent decomposition pathways, the first consisting in a 1,2‐elimination and the second requiring the implication of hydroxyl hydrogen. This last process and other decomposition routes suggest the presence of H. bridging between the hydroxyl oxygen atom and fluorine.
