在Mn VII和Fe VIII的光谱中，已发现了3d D2，4p P2，5s S2，6s S2和几个nf F2项的极紫外谱线。在Cr VI中发现了3d D 2− n f F 2系列的第一个成员，这些光谱是用21英尺掠入射真空摄谱仪拍摄的。通过使用恒定的二阶差分位移频率图，便于识别。
Lines in the extreme ultraviolet region involving the 3 d D 2, 4 p P 2, 5 s S 2, 6 s S 2, and several nf F 2 terms have been identified in the spectra of Mn VII and Fe VIII. In Cr VI the first member of the 3 d D 2− n f F 2 series has been found. These spectra have been photographed with a twenty-one foot grazing incidence vacuum spectrograph. Identification was facilitated by the use of constant second difference displaced frequency diagrams.
