“…Using the obtained hf constants, the wavenumbers of the lines can be determined precisely, this can lead to improved energy levels. In the future, we will work on determining accurate energies of the Sc I levels as done for the other elements in [26][27][28].…”

Fourier Transform Spectra of Scandium were analyzed, and hyperfine structure constants of odd and even levels of the configurations 3d2(4p+5p+4s+5s+4d), 3d4s(4p+5p+5s+6s+4d+5d), 3d3, 3d4p2,and 4s2(4p+4d) are determined. The hyperfine structures extracted from FT spectra were simulated and fitted to find the hf structure constants. A total of 104 even levels and 95 odd levels hf constants of Sc I are determined. The values of hf constants were compared with the published data, and a good agreement was found between them. The hf constants of 10 odd and 11 even levels are new. Seven hf constants values have been modified. Two software Fitter programs and classification of spectral lines were used to fit and simulate the spectral line’s hyperfine structure in Scandium’s FT spectra.

In Atoms2020, 8, 23; doi:10.3390/atoms8020023, we reported on a complete optogalvanic (OG) spectrum of a discharge burning in a La–Ar gas mixture, in the spectral range 5610–6110 Å (17,851 to 16,364 cm−1). Now we are able to communicate further new energy levels, found via searching for laser-induced fluorescence lines when exciting unclassified lines from the OG spectrum. We were able to find 17 new levels, and for two further levels, the line list has extended. With the help of these 19 levels, we could classify 132 spectral lines.
