摘要: Calculations, using the Improved Virtual Orbital technique and equivalent cores concepts, of shake-up spectrum H2O are reported, results compared with previous ΔSCF-type calculations. Both fluorine oxygen optimized basis sets have been used. The methods appear to give satisfactory results, although calculated intensities rather uncertain. A CI calculation, in which all states allowed interact, indicates fairly substantial interaction between some cases.
