The basis set polarization approach is applied to the generation of medium-size polarized GTO/CGTO basis sets for accurate calculations of molecular dipole moments and polarizabilities. The polarized basis sets determined in this paper for H and C through F are employed in SCF HF and MBPT calculations of dipole moments and polarizabilities of FH, H2O, NH3, and CH4. The excellent results obtained at both the SCF HF and MBPT(4) levels of approximation indicate that the present basis sets can be employed for the accurate high-level correlated studies of relatively large molecules The use of those basis sets in calculations of intermolecular interactions is also discussed.

The idea of what is called the basis set polarization method is reviewed and the available polarized basis sets are surveyed. Following the basis set polarization approach and certain empirical rules developed earlier, the first-order polarized basis sets for the Group IIIA elements are generated. These basis sets have been developed for both nonrelativistic and spin-averaged Douglas-Kroll relativistic calculations. Their performance is tested in calculations of atomic dipole polarizabilities and in high-level-correlated calculations of the dipole moments of GaF, InF, and TlF. The relativistic effects have been found to significantly affect the calculated molecular dipole moments of the studied fluorides. The results are in satisfactory agreement with reference data. The present study completes the library of the first-order polarized basis sets for all atoms of the main groups of the Periodic Table.

Polarized bases set approach has been applied for preparation of medium-size contracted GTO basis sets starting from various standard energy-optimized and even-tempered isotropic atomic basis sets. Their usefulness for calculation of the SCF interaction energy and its components as well as dispersion energy consistently determined within the dimer basis set were studied for He2 and Be2 systems for intermediate internuclear separations. The results obtained with polarized basis sets indicate their good performance in comparison with property oriented ones.
