　　It is traditional for quantum theory of molecular systems（molecular quantum chemistry） to describe the properties of amany-atom system on the grounds of in- teratomic interactionsapplying the linear combination of atomic orbitals （LCAO）approximation in the electronic-structure calculations. The basisof the theory of the electronic structure of solids is theperiodicity of the crystalline potential and Bloch- typeone-electron states， in the majority of cases approximated by alinear combina- tion of plane waves （LCPW）. In a quantum chemistryof solids the LCAO approach is extended to periodic systems andmodified in such a way that the periodicity of the potential iscorrectly taken into account， but the language traditional forchemistry is used when the interatornic interaction is analyzed toexplain the properties of the crystalline solids. At first， thequantum chemistry of solids was considered simply as theenergy-band theory　or the theory of the chemical bond intetrahedral semi-conductors . From the beginning of the 1970s theuse of powerful computer codes has become a common practice inmolecular quantum chemistry to predict many properties of moleculesin the first-principles LCAO calculations. In the condensed-matterstudies the accurate de*ion of the system at an atomic scalewas much less advanced .
