在9753-9997 A（10000-10250 cm ~（-1））范围内研究了钴氖空心阴极灯的高分辨傅里叶变换发射光谱。在Co II 3d 7（4F）5g子组态的54个能级中，有51个是通过144个新发现的跃迁到3d 7（4F）4f子组态的能级而发现的。这些线占大多数以前未分类的过渡在这个光谱区域。能级的精度为几mK（1 mK = 0.001 cm-1）。JK耦合被用来代表4f和5g的水平和适用性，这是通过应用四极近似。一个分类的线性观测到的4f-5g跃迁给出了精确到约0.003 cm-1的强线，观测到的强度，和计算的振子强度的波数。
The high resolution Fourier-transform emission spectrum from a cobalt-neon hollow cathode lamp has been studied in the region 9753–9997 A (10000–10250 cm-1). Of the 54 levels of the Co II 3d7(4F)5g subconfiguration, 51 are found by means of 144 newly identified transitions to the levels of the 3d7(4F)4f subconfiguration. These lines account for the majority of previously unclassified transitions in this spectral region. The accuracy of the energy levels is a few mK (1mK = 0.001 cm-1). JK coupling is used to represent the 4f and 5g levels and the suitability of this is shown by applying the quadrupolic approximation. A classified linelist of the observed 4f–5g transitions is given with wavenumbers accurate to approximately 0.003 cm-1 for strong lines, observed intensities, and calculated oscillator strengths.
