The stereochemistry and the chiropticalproperties of the nonplanar nitrosamine group were investigated by means of nonempirical quantum chemical calculations on 1-nitrosoaziridine, (2R)-2-methyl-1-nitrosoaziridine, and (2S,3S)-2,3-dimethyl-1-nitrosoaziridine, and by experimental measurement of the CD spectra of compounds 2, 3, (2S)-2-carbomethoxy-1-nitrosoaziridine, and (2S,3S)-2,3-bis(isopropoxy
