The pure rotational spectra of Sc79Br and Sc81Br have been measured in two vibrational states (v=0 1) the 5–24 GHz spectral region, using a cavity pulsed jet Fourier transform microwave spectrometer. samples were prepared by ablating Sc metal presence Br2 contained Ar backing gas jet. equilibrium internuclear distance re has determined along with estimates for harmonic vibration frequency ωe dissociation energy, De. Nuclear quadrupole coupling constants spin–rotation both Br. ionic character ScBr bond is estimated to be ∽95%. Magnetic shieldings nuclei estimated.
