| Abstract: | Coupled pair approximation and configuration interaction calculations were carried out on the gallium fluoride molecule and its positive ion with flexible basis sets. Spectroscopic constants of these species were examined in detail through step-wise extensions of correlating space. The contribution from correlations of the semi-core 3d electrons in Ga was found to be sizable. The bonding character was revealed to be highly ionic even for the positive ion.
