摘要
Ab initio calculations of p-dichlorobenzene molecule were carried out using the Hartree-Fock method in the 6-31G* valence-split basis set. The molecule was also calculated by the MNDO method in the valence sp-basis set for comparison. The populations of the valent p-orbitals of the C and Cl atoms were analyzed. The optimized geometry of the molecule as well as its Cl-35 NOR frequency and the asymmetry parameter of the electric field gradient at the Cl-35 nuclei calculated using the populations of the less diffuse components of the valent p-orbitals of the Cl atoms are in agreement with the corresponding experimental values for the alpha-modification of 1,4-Cl2C6H4.
