✦ Synopsis


In semi-cmpiricnl molcculnr orbital cnlculntions it is frcqucntly desirable to include in the basis set of atomic orbitals low energy virtual atomic orbitnls. Criteria for representing the spectroscopically obscrvcd virtual orbitxls by single Slnter-type orbitnls @TO) are discussed. Representations for atoms through polonium (excluding the kmthnnide series) are proposed.
