This paper presents an extension to our knowledge of ∆v = 1 and ∆v = 2 bands of carbon monoxide in the ground state, measured by Fourier transform infrared spectroscopy of glow discharge of formamide-nitrogen mixture. Lines in declared bands are measured up to v = 30 for ∆v = 1 and up to v = 24 for ∆v = 2 band, by use of both InSb and MCT detectors, which have not been measured in the laboratory before. Dunham parameters obtained by fitting our lines are presented as well as comparison to other authors. The paper also demonstrates the interesting impossibility of sufficient population of ∆v = 2 band of CO when only pure CO is used in the glow discharge, instead of formamide-based mixture. Additionally, we present a non-LTE model to describe the intensity pattern of the ∆v = 1 and the ∆v = 2 bands of ¹²C¹⁶O experimental spectra by simulating the corresponding non-LTE vibrational populations of CO.

本文介绍了我们 对基态一氧化碳的∆ v  = 1和∆ v = 2谱带的认识的扩展，该光谱通过甲酰胺-氮混合物辉光放电的傅里叶变换红外光谱法进行测量。 通过使用InSb和MCT检测器（在实验室中尚未进行过测量），对声明的频段中的线进行测量， 对于∆ v  = 1最高可达v = 30， 对于∆ v = 2频段最高可达v = 24 。介绍了通过拟合线获得的Dunham参数，并与其他作者进行了比较。本文还证明了足​​够的∆ v种群的有趣可能性 =仅在辉光放电中使用纯CO代替甲酰胺基混合物时，CO的2条带。此外，我们提出了一个非LTE模型，通过模拟相应的CO非LTE振动种群，描述了¹² C ¹⁶ O实验光谱的∆ v  = 1和∆ v  = 2谱带的强度模式。
