Proceedings of the second All-Union conference of solid-state quantum chemistry

In this conference such topics as the electronic structure of d-metal compounds, cluster model and calculation of the electronic structure of covalent solids, and molecular models in the quantum-chemical investigation of the structure of defect centers on oxide catalysts are discussed. An investigation of the electronic structure of defects in tetrahedral semiconductors by the Green's-function method is offered, as is a discussion on the role of fluctuations in exciton absorption of light in the exciton theory of defect formation. Experimental data is offered on short-range order in noncrystalline solids, and current problems in the theory of disordered semiconductors are discussed
