An extensive analysis of the Mn spectrum was carried out using high-resolution Fourier transform (FT) and grating spectroscopy of Mn–Ne and Mn–Ar hollow cathode discharge sources, over the range 82–5500nm (1820–121,728 cm⁻¹). Spectral wavelengths for a total of 6019 Mn ii lines have been measured, of which 1345 are obtained through FT spectroscopy. These wavelengths are given to at least an order of magnitude lower uncertainty than previous measurements. These lines were used to identify 6256 Mn ii transitions and improve the values of 505 previously published energy levels with typical uncertainties of a few thousandths of a cm⁻¹, representing an order-of-magnitude reduction in uncertainty. We have verified and improved an additional 57 Mn ii energy levels, previously established through observation of stellar spectra alone, using our FT spectra. In addition, 52 new energy level values have been established. The number of classified lines reported is approximately 50% more than previously published. The new accurate data for 614 energy levels and 6019 lines will allow a more reliable analysis of Mn ii spectral lines in astrophysical spectra.

使用高分辨率傅立叶变换（FT）和Mn-Ne和Mn-Ar空心阴极放电源的光栅光谱对Mn光谱进行了广泛的分析，范围为82-5500nm（1820-121,728 cm ^-1）。已经测量了总共6019条Mn ii谱线的光谱波长，其中1345条是通过FT光谱法获得的。这些波长的不确定度至少比以前的测量低一个数量级。这些线用于识别6256 Mn ii跃迁并提高505以前发布的能级值，其典型不确定度为几分之一cm ^-1，表示不确定性降低了一个数量级。我们已经使用FT光谱验证并改善了之前仅通过观察恒星光谱确定的57 Mn ii能级。此外，已经建立了52个新的能级值。报告的分类行数比以前发布的大约多50％。614能级和6019谱线的新的准确数据将使天体物理光谱中Mn ii谱线的分析更加可靠。
