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.

对称13C氰，13C2N2的受激拉曼光谱

已经通过受激拉曼技术以接近多普勒的分辨率研究了氰 13C214N2 的拉曼光谱。nu1 (2260 cm-1) 和 nu2 (835 cm-1) 振动带头周围的区域已被记录。除了基本面之外，还观察到了由 v5 = 1-3 和 v4 = 1 引起的热带。已检测到许多强扰动。已经分析了光谱并获得了激发态的旋转常数。已经进行了拉曼轮廓的计算机模拟，作为对分配的测试。在 nu1 区域也观察到了一些弱的 DeltaJ = -2 线。
