SCHEDULED MAINTENANCE
Infrared intensities show that the proton attached to nitrogen in tetrahydro-1,2-oxazine exists predominantly in the equatorial position. For an N-methyl group, the equatorial position is favoured by ca. 1·9 kcal mol–1, as deduced from electric dipole moments. The conformations of di- and tri-methylhydroxylamines are discussed.
