their limitations. Refinements of the two approaches (Configuration Interaction for MO, ionic
terms in VB). Qualitative description of LCAO-MO treatment of homonuclear and heteronuclear
diatomic molecules (HF, LiH). Localised and non-localised molecular orbitals treatment of
triatomic (BeH 2, H 2O) molecules. Qualitative MO theory and its application to AH 2 type
molecules.
