✦ Synopsis

Three isotopically enriched samples of ethylenimine [aziridine] hare been prepared, namely, mixtures containing ca. 50 % [2-D]ethylenimine, 25 % [2,2'-Dzlethylenimine, and 25 % parent molecule; 97 % f15N]ethylenimine and 3 parent molecule; 64 % [Wlethylenimine and 36 % parent molecule. Infrared gas spectra showed the samples (ca. 90mg) to be of high chemical purity (>98 %I. The preparations have been used successfully for high-resolution microwave studies.
