In 1937, Meggers and Scribner published a paper on arc and spark spectra of ytterbium providing wavelengths, relative intensities, and spectrum numbers of 1668 spectral lines, including about 400 for Yb I, 1250 for Yb II, and 12 for Yb III. That work was handicapped by impure materials and conventional light sources. When pure ytterbium metal and new light sources became available in 1950, Meggers and Corliss decided to make a new description of ytterbium spectra. This new description includes data for 7300 spectral lines with wavelengths between 2000 Å and 12000 Å distributed as follows: 1800 belong to Yb I, 5100 to Yb II, 430 to Yb III, and 5 to Yb IV. The Zeeman effect on 1300 lines has been observed in magnetic field intensities ranging from 3.7 to 9.358 tesla (37000 to 93580 gauss). These data were obtained for chemical identifications and for structural analyses of the first two spectra of ytterbium.
1937年，梅格斯和斯克里布纳发表了一篇关于镱的电弧和火花光谱的论文，给出了1668条谱线的波长、相对强度和光谱编号，其中包括约400条镱I谱线、1250条镱II谱线和12条镱III谱线。这项工作受到不纯材料和传统光源的限制。1950年，当纯镱金属和新光源问世后，梅格斯和科利斯决定对镱光谱进行新的描述。这一新描述包括了7300条谱线的数据，这些谱线的波长在2000埃至12000埃之间，分布如下：1800条属于镱I，5100条属于镱II，430条属于镱III，5条属于镱IV。在3.7至9.358特斯拉（37000至93580高斯）的磁场强度范围内，已观察到1300条谱线的塞曼效应。这些数据是为镱的前两个光谱的化学鉴定和结构分析而获得的。
