The ab initio quantum-chemical calculations were used to obtain the components of the dipole moment of four molecules composed of a rigid central segment and two symmetric flexible endings. The recently synthesized molecules are of interest due to th

Using the methods developed in part I the self-trapping energy of the VK centre on and below the surface has been calculated for NaCl and KCl crystals. It is found that the energy decreases monotonously by approaching the external surface. Conclusion

A simple theoretical model of the Vk-centre situated on the (001) external surface of the f.c.c. alkali halide crystal has been derived. The energy of the VK-centre calculated for the case of KCI using this model appeared to be about 0.49 eV less the
