Abstract
The emission spectra of the A2Ð-X2Σ+ (red) system of 12C14N have been reinvestigated in the 3500-22 000 cmâ1 region at high resolution using a Fourier transform spectrometer. In total, spectra of 63 bands involving vibrational levels up to vâ²Â = 22 of the A2Ð state and vâ³Â = 12 of the X2Σ+ ground state have been measured and rotationally analyzed providing an improved set of spectroscopic constants. The present measurements of the Îv = â2 sequence bands of 12C14N and those of 13C14N from Ram et al. (2010) [36] allow for a much improved identification of these two isotopologues in the near infrared spectra of carbon stars.
