• New magnetic dipole hyperfine structure (HFS) constants A of Sc I and Sc II were derived by analyzing of the transition lines ranging from 3998 to 39,979  cm - 1 in the Fourier-transform (FT) spectra which was recorded in the US National Solar Observatory. In this work, we determined the HFS constants for 56 levels of Sc I from 14,926.061 to 41,162.506 cm - 1 and for 12 levels of Sc II from 30,815.70 to 77,387.17 cm - 1 . To our best knowledge, the HFS constants for 50 out of 56 levels in Sc I and for nine out of 12 levels in Sc II are reported for the first time. Our results have good agreements with the experimental values reported in the literature. Most of the estimated uncertainties are less than 10%. Graphic abstract
