A comprehensive list of the best measured wavelengths in the In II spectrum has been compiled. Uncertainties of the wavelength measurements have been analyzed, and existing inconsistencies have been resolved. An optimized set of fine-structure energy levels that fits all observed wavelengths has been derived. Uncertainties of the energy level values have been reduced by an order of magnitude. An improved value of the ionization limit of In II has been determined by fitting quantum-defect and polarization formulas for several series of levels. Intensities of lines observed by different authors have been analyzed and converted to a uniform scale. A set of recommended values of radiative transition rates has been critically compiled, and uncertainties of these rates have been estimated. The hyperfine structure interval in the 5s (2)S ground state of In III has been determined from the measurements of the 5sng and 5snh series in In II.
已编制出铟 II 光谱中最佳测量波长的综合列表。分析了波长测量的不确定度，并解决了现有的不一致问题。推导出了一组优化的精细结构能级，该能级与所有观测波长相符。能级值的不确定度已降低了一个数量级。通过拟合几个能级系列的量子亏损和极化公式，确定了铟 II 电离极限的改进值。分析了不同作者观测到的谱线强度，并将其转换为统一的标度。严格编制了一组辐射跃迁速率的推荐值，并估计了这些速率的不确定度。通过对铟 II 中 5sng 和 5snh 系列的测量，确定了铟 III 的 5s(2)S 基态的超精细结构间隔。
