The samples were prepared by ablating Sc metal in the presence of Br-2 contained in the Ar backing gas of the jet. The equilibrium internuclear distance r(e) has been determined along with estimates for the harmonic vibration frequency omega(e) and the dissociation energy, D-e. Nuclear quadrupole coupling constants and spin-rotation constants have been determined for both Sc and Br. The ionic character of the ScBr bond is estimated to be similar to 95\%. Magnetic shieldings for both nuclei have been estimated.}, keywords = {HYPERFINE, MOLECULAR-BEAM, MONOBROMIDE, RF DOUBLE-RESONANCE, SCANDIUM, SPECTROSCOPY, STATE, SYSTEM, YTTRIUM}, isbn = {1463-9076}, url = {://000084333800006}, author = {Lin, W. and Evans, C.
