The rotational and rotation‐vibrational Raman spectra of 14N2, 14N15N and 15N2

Abstract

AbstractThe pure rotational and rotation‐vibrational Raman spectra of 14N2, 14N15N and 15N2 have been photographed using a previously described instrument. The analyses of the bands yield for each molecule v0, B0, B1‐B0 and D. From the values of B0 and B0‐B1 the internuclear distances re 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 re is 1.097701 ± ± 0.000004 Å.
