The negative ion mass spectra of methanol, methanol‐ d and trideuteromethanol have been measured at 70 eV. Use of deuterated methanols has enabled the ion at m / e 31 to be identified as CH 3 O − and not CH 2 OH − . Isotope effects have been determined for H − and D − formation, and for OH − and OD − formation. It has been shown that OH − formation occurs as a rearrangement reaction as well as by simple CO bond fission.
