Fourier transform emission spectroscopy of the A2Π–X2Σ+ (red) system of 13C14N (II)

摘要: Abstract High resolution emission spectra of the A2Π–X2Σ+ transition 13C14N have been measured in 15 000–24 000 cm−1 region. Molecules were produced by reaction 13CH4 and 14N2 an active nitrogen afterglow discharge. The recorded using Fourier transform spectrometer associated with McMath-Pierce Solar Telescope National Observatory. A rotational analysis 27 bands involving excited state vibrational levels v′ = 9–22 ground up to v″ = 12 has obtained. An improved set spectroscopic constants determined for v = 0–22 A2Π combining present measurements those reported previously v = 0–8 [Ram et al., Astrophys. J. Suppl. Ser. 188 (2010) 500] existing infrared millimeter-wave 13C14N. 6–3, 7–4, 8–5 9–6 B2Σ+–A2Π also identified 23 300–24 000 cm−1 region included final analysis. experimental line list calculated term values are provided.
