The [Formula Presented] and [Formula Presented] spectra from metallic scandium, the first of the [Formula Presented] transition elements, were measured using a high-resolution curved crystal spectrometer. The spectrometer resolution was determined employing a narrow emission line from pionic neon. The parameters of the resolution-corrected spectrum are extracted and compared to previous studies and theory. Fits to ab initio relativistic Dirac-Fock calculated spectra show that the [Formula Presented] spectrum can be accounted for using an isolated-atom model with diagram, [Formula Presented]- and [Formula Presented]- spectator hole transitions. The [Formula Presented] spectrum, however, cannot be fitted by such isolated-atom multiplets and may require employing nonlocalized bonding orbitals.
