The ability of ab initio quantum-chemical methods to produce very accurate potential energy curves for van der Waals molecules is demonstrated through the calculation of the helium dimer interaction energy for a variety of internuclear distances around the van der Waals minimum (R= 5.6 bohr).

β¦ Synopsis
The potential energy and dipole moment functions of the X 2fI ground state of the GeH radical have been computed using highly correlated SCEP CEPA electronic wavefunctions.
The calculated dipole moment pa in the vibrational ground state is 0.16 D (Ge+ H-). This result questions the value of 1.24 D derived by Brown, Evenson and Sears from a comparison of intensities of electric and magnetic dipole transitions. The GeH radical is predicted to be a strong infrared emitter.

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
The structures and dipole moments of the four low-lying electronic states (X 211, A \*A, B 'C -and C \*Z ' ) of the linear CCN radical are investigated by ab initio calculations at SDCIlDZP and TZP levels. For all the electronically excited states, the dipole moments are calculated to be z 3.0 D. Ho
The ab initio effective valence shell Hamiltonian method, which is based upon quasidegenerate many-body perturbation theory, has been extended to calculate molecular properties. This new method is applied to the study of dipole moment functions of the OH molecule and its ions. The calculated results
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
