Ring cleavage α to the oxygen function leads to [C 3 H 5 O] + and [C 4 H 7 O] + ions in the mass spectra of 4‐arylcyclohexanols and their methyl ethers, respectively. Cleavage α to the aryl group gives rise to [C 3 H 7 O] + (from the alcohols), [C 4 H 9 O] + (from the ethers) and [ArC 3 H 4 ] + (from both) ions. The competition between the two ring cleavages explains the effect of the substituents of the aryl groups on the relative abundances of the resulting ions.
