title: The Stimulated Raman Spectrum of Symmetric 13C Cyanogen, 13C2N2.
abstract: 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 v4 = 1 have been observed. A number of strong perturbations have been detected. The spectra have been analyzed and rotational constants for the excited states have been obtained. Computer simulations of the Raman contours have been carried out as a test of the assignments. A few weak DeltaJ = -2 lines have also been observed in the nu1 region.
