Abstract : Summaries of four papers presented at the International Symposia on Molecular Structure and Spectroscopy in Japan in September 1962: (1) Connection between partitioning technique, perturbation theory, and variation principle in the quantum theory of atoms and molecules. (2) The Huckel approximation in the theory of conjugated system in view of recent progress in treating the many-electron wave equation. (3) Change of bond lengths under addition and substitution and Pauling's concept of electronegativity treated by partitioning technique. (4) Quantum theory of the electronic and protonic structure of large molecules. (Author)
