A model of the formation of sequences of stereochemical configurations in chain macromolecules that was proposed by Coleman and Fox is considered. Previously, it was thought that this model can not be represented by Markov statistics of any order. On

The use of the deterministic model of chain growth for the copolymerization of vinylidene fluoride and hexafluoropropene instead of the classical Markov model makes it possible to correctly relate the data of the 19F NMR spectra of copolymers with di

The semiempirical MO method SENDO1 is developed for the treatment of extended systems. The Large Unit Cell (LUC) approach is incorporated to achieve feasibility of calculations in real space. We present the resulting formulas and discuss convergence

The use of symmetry-adapted linear combinations (SALC) of atomic orbitals in large unit cell (LUC) calculations of solids is considered. A procedure is proposed of SALC generation being convenient for the automation in computer calculations. It is sh

It is shown that the use of the simple cubature formula for the approximate calculation of the density matrix Qrr in the non-local Hartree-Fock exchange for crystals leads to a non-physical divergence of the lattice sums. To overcome this difficulty

The energy band structure of corundum is investigated theoretically using the semiempirical Mulliken-Rudenberg method. A crystal potential is constructed basing on the self-consistent effective atomic charges and electronic populations obtained withi
