The pure rotational and rotation‐vibrational Raman spectra of 14 N 2 , 14 N 15 N and 15 N 2 have been photographed using a previously described instrument. The analyses of the bands yield for each molecule v 0 , B 0 , B 1 ‐ B 0 and D . From the values of B 0 and B 0 ‐ B 1 the internuclear distances r e are calculated independently for each species. Within the experimental accuracy the distances are identical as required by the Born‐Oppenheimer approximation. The mean value for r e is 1.097701 ± ± 0.4 Å.
