## Abstract Calculations of molecular polarizabilities require basis sets capable of accurately describing the responses of the electrons to an external perturbation. Unfortunately, basis sets that yield suitable quantitative results have traditionally been all‐electron sets with large numbers of p

Abstract
Electric polarizabilities are calculated by solving the first‐ and second‐order perturbation equations through a variational procedure. Satisfactory numerical results are obtained for a number of molecules using the CNDO approximation with an extended basis set.

## Abstract Following the recent studies of basis sets explicitly dependent on oscillatory external electric field we have investigated the possibility of some further truncation of the so‐called polarized basis sets without any major deterioration of the computed data for molecular dipole moments,
Ab initio MO geometry optimization studies on a number of molecules containing second-row atok using various palariiation basis sets are presented. In particular the use of gaussian bond functions is shown to be a good substitute for the more conventional (and expensive) atomcentred d functions. Mol
The structures of the ground state phenoxy radical and phenylnitrene were calculated by the UNO-CAS method and compared with CAS-SCF results. The two methods produce almost identical structures which arc very sensitive to polarization functions in the basis sets. On going from the 3-2 1G to the 6-31
