CN VIBRATION-ROTATION SPECTRUM

CN vibration-rotation bands for the sequences (1-0) through (4-3) and (2-0) through (4-2) were observed in a King furnace and measured in the spectral regions 1797-2208 and 3740-4156 cm-1 with the McMath Fourier-transform spectrometer at the National Solar Observatory. Of the 489 lines observed, the wave numbers of 454 were fitted with a linear least-squares algorithm in order to calculate equilibrium Dunham coefficients, which will reproduce the lines with a standard deviation of 0.004 cm-1.
