Abstract
Abstract The molecular structures of O -methylhydroxylamine, N -methylhydroxylamine, N , O -dimethylhydroxylamine and N , N , O -trimethylhydroxylamine in the gas phase have been determined by electron diffraction. In each case, the principal conformer present had the anti conformation about the N-O bond, but the dimethyl- and trimethyl-hydroxylamines also had 20–30% of the syn conformer. The N-O bond lengths increase with methyl substitution, from 146.3(3) pm in NH 2 OMe to 151.3(9) pm in Me 2 NOMe; C-N bond lengths also increase, but C-O bond lengths show a decrease.
