## Abstract The nature of the interaction between nucleic acids and divalent ions in solution is complex. It includes longβrange electrostatic and shortβrange nonelectrostatic forces. Water molecules can be in an inner coordination shell that intervenes between the ion and its binding site. This wo

β¦ Synopsis
Semi-empirical I-dependent pseudopotentials have been used in the MRCI(SD) calculation of the adiabatic potentials and dipole transition moments for the ZnHg and ZnCd pairs. Only the valence electrons of the system are treated explicitly. The atomic cores are simulated by the energy-adjusted pseudopotentials.
The spin-orbit coupling has not been considered.

We studied the transferability of the localized orbitals (LOs) of interacting Ne atoms using several basis sets. Both at SCF and at MP2 and MP3 levels, the contributions of the LOs have been calculated and discussed for the Nez and Ne, systems. It was shown that for the LOs the transferability is s
Practical improvements for the semi-empirical calculation of long-range and short-range energies between two arbitrary molecules are given. Interaction energies between molecules or' organic solvents are calculated and compared with experimental vaporization energies.
The recently proposed ab initio method for calculations on molecular systems with the approximation of the inactive part of a molecule by a frozen molecular fragment is applied to the case of ethanol-water interactions. The results from the Hartree-Fock and second-order Msller-Plesset methods are pr
