The mass spectra of benzophenone oxime O ‐methyl and O ‐methylthiomethyl ethers, α,α‐diphenyl‐ N ‐methyl and methylthiomethyl nitrones, and some deuterated analogues, are reported. Fragmentation pathways are discussed, with particular reference to the structures of ion m / e 211 found in all the spectra. Some evidence suggests nitrone → O ‐ether rearrangement at either neutral molecule or molecular ion level.
