In this study, the hyperfine structure constants of Scandium were analyzed using Fourier Transform Spectra. The hf constants of 104 even levels and 95 odd levels were determined and compared with published data, showing a good agreement in most cases. Additionally, hf constants for 8 odd and 10 even levels were determined for the first time from experimental data, and modifications were made to seven HFS constants.
Fourier Transform Spectra of Scandium were analyzed, and hyperfine structure constants of odd and even levels of the configurations 3d(2)(4p + 5p + 4s + 5s + 4d), 3d4s(4p + 5p + 5s + 6s + 4d + 5d), 3d(3), 3d4p(2), and 4s(2)(4p + 4d) are determined. The hyperfine structures (HFS) extracted from FT spectra were simulated and fitted to find the corresponding A-values. For 104 even levels and 95 odd levels, hf constants of Sc I were determined. The values of HFS constants were compared with published data, and a good agreement was found for most of them. The hf constants of 8 odd and 10 even levels were determined for the first time from experimental data. Seven HFS constants values have been modified.
