The mass spectra of 1,2‐cyclohexene oxide and three deuterium labeled analogs are discussed and mechanistic rationalizations are given for the major fragmentation processes observed. Multiple mechanisms are required to explain the indicated peak shifts in the labeled analogs for many of these ions, thus demonstrating again the care that needs to be exercised in the interpretation of the mass spectra of relatively simple molecules.
