Spectra of Yb IV produced with a low voltage sliding spark discharge were photographed in the range of 700-2200 Å with a 10.7 m normal incidence spectrograph. Wavelengths for 944 spectral lines identified as Yb IV were measured. Of these, 535 were classified as transitions between 95 even and 51 odd energy levels of the 4 , 4 5, 4 6s, and 4 6 configurations. Values for the interaction parameters were derived by a least squares fit to the known levels.
用低电压滑动火花放电产生的镱四价离子光谱，使用10.7米正入射光谱仪在700 - 2200埃范围内进行了拍摄。测量了被认定为镱四价离子的944条谱线的波长。其中，535条谱线被归类为4、4 5、4 6s和4 6组态的95个偶能级与51个奇能级之间的跃迁。通过对已知能级进行最小二乘法拟合得出相互作用参数的值。
