Using a linked-parametric technique of level-fitting calculations in a multiconfiguration basis, a parametric fine structure (fs) analysis for both even and odd parities of Cr II was achieved. For the first time the fs parameter, magnetic Landé $g$-factor and the percentage of leading eigenvector values for more than one thousand levels are determined and given for these two sets. This study has led us to confirm in the whole the well founded basis of NIST team works but inevitably also to exchange assignments of some levels classified in earlier lists of energy levels and to shift positions of some quartets like ${}^4{F}_J$ for instance. Furthermore we take this opportunity to add our predicted doublet, quartet and sextet locations for missing experimental levels up to 124,000 cm⁻¹.

使用链接参数技术在多配置基础上的水平拟合计算，可以实现Cr II奇偶校验的参数精细结构（fs）分析。首次使用fs参数，磁性Landé$G$确定并给出了这两个集合的系数和前导特征向量值的百分比（超过一千个水平）。这项研究使我们在总体上确认了NIST团队工作的良好基础，但不可避免地还交换了归类于较早的能级列表中的某些能级的分配，并改变了诸如${}^4{F}_{Ĵ}$例如。此外，我们借此机会添加了我们预测的双峰，四重奏和六重奏位置，以弥补高达124,000 cm ^-1的缺失实验水平。
