內容簡介

It is traditional for quantum theory of molecular systems （molecular quantum chemistry） to describe the properties of a many-atom system on the grounds of in- teratomic interactions applying the linear combination of atomic orbitals （LCAO） approximation in the electronic-structure calculations. The basis of the theory of the electronic structure of solids is the periodicity of the crystalline potential and Bloch- type one-electron states， in the majority of cases approximated by a linear combina- tion of plane waves （LCPW）. In a quantum chemistry of solids the LCAO approach is extended to periodic systems and modified in such a way that the periodicity of the potential is correctly taken into account， but the language traditional for chemistry is used when the interatornic interaction is analyzed to explain the properties of the crystalline solids. At first， the quantum chemistry of solids was considered simply as the energy-band theory or the theory of the chemical bond in tetrahedral semi-conductors . From the beginning of the 1970s the use of powerful computer codes has become a common practice in molecular quantum chemistry to predict many properties of molecules in the first-principles LCAO calculations. In the condensed-matter studies the accurate description of the system at an atomic scale was much less advanced .
