对傅里叶变换光谱仪在红外波长区域记录的钛光谱进行了分析，并确定了 572 条谱线为 3d-4f、4d-4f 和 4-5g 类型的跃迁。 2400埃左右的UV区域中的11条谱线已被确定属于3d(3)4s a(5)F-3d(2)4s(F-4)4f跃迁阵列。已经建立了113个级别的3d(2)4s(F-4)4f、3d(3)(F-4)4f和3d(2)4s(F-4)5g子配置。还发现了六个新的 4D 关卡。已知 Ti I 能级的数量增加了 25% 以上，分类线的数量增加了 20%。对 4f 和 5g 配置进行的参数研究表明，JK 耦合近似可以最好地描述该结构。 （较少的）
Titanium spectra recorded in the infrared wavelength region with a Fourier Transform Spectrometer have been analysed, and 572 lines have been identified as transitions of the types 3d-4f, 4d-4f and 4-5g. 11 lines in the UV region around 2400 angstrom have been identified as belonging to the 3d(3)4s a(5)F-3d(2)4s(F-4)4f transition array. 113 levels of the 3d(2)4s(F-4)4f, 3d(3)(F-4)4f and 3d(2)4s(F-4)5g subconfigurations have been established. Also six new 4d levels have been found. The number of, known Ti I energy levels has been increased by more than 25% and the number of classified lines by 20%. A parametric study of the 4f and 5g configurations has been performed, showing that the structure is best described by the JK coupling approximation. (Less)
