CN vibration–rotation spectrum

Abstract

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.
