The dipole moment, static polarizability and hyperpolarizabilities of hydrogen peroxide, H202, have been determined in large-scale ab initio calculations using the coupled cluster method, CCSD(T). The dependence of the calculated properties on the torsional HOOH angle is discussed. At the CCSD(T)/au

β¦ Synopsis
An ab initio treatment of the molecular geometry and static dipole polarizability for naphthalene in its electronic ground state is reported, using the coupled perturbative Hartree-Fock method. It is shown that the 6-31 +G and the 6-311 +G basis sets both give polarizability values that are in excellent agreement with the experimental values found from Stark spectroscopy and from measurements made in solution and in the solid state. Electron correlation was treated using the MP2 approach, and we report that these correlation effects are negligible in the polarizahility calculation when using the HF/6-31G basis set.

The static polarizabilities, or, of various xanthone analogues (1-19) were estimated by ab initio molecular orbital calculations using the coupled perturbed Hartree-Fock (CPHF) method. The influence of basis sets on the calculated values was examined in detail and the reliability of the ECP approach
The two structures of azulene with Clv and C, symmetry, their energy difference and their dipole moments have been investigated via ab initio quantum mechanics. Self-consistent-field (SCF) theory was used in conjunction with various basis sets up to TZP+f quality. The SCF method fails to predict the
