Abstract
The preparation of the unsymmetrically isotope‐labelled title compounds was achieved in pure form for the first time. While mono‐^15^N‐cyanogen is available in a two‐step‐synthesis, the preparation of mono‐^13^C‐cyanogen requires five steps, the last step in both cases being the dehydration of mono‐^15^N‐e.g. mono‐^13^C‐oxamide with phosphorus pentoxide.

The Raman spectrum of cyanogen 13C214N2 has been investigated at nearly Doppler resolution by means of a stimulated Raman technique. The regions around the bandheads of the nu1 (2260 cm-1) and nu2 (835 cm-1) vibrations have been recorded. Besides the fundamentals, hot bands arising from v5 = 1-3 and
