Three isotopically enriched samples of ethylenimine [aziridine] have been prepared, namely, mixtures containing ca. 50% [2‐D]ethylenimine, 25% [2,2′‐D 2 ]ethylenimine, and 25% parent molecule; 97% [ 15 N]ethylenimine and 3% parent molecule; 64% [ 13 C]ethylenimine and 36% parent molecule. Infrared gas spectra showed the samples (ca. 90 mg) to be of high chemical purity (>98 %). The preparations have been used successfully for high‐resolution microwave studies.
