Reliable isotropic and anisotropic dipole properties, and dipolar dispersion energy coefficients, for CO evaluated using constrained dipole oscillator strength techniques

Abstract

Abstract Constrained anisotropic dipole oscillator strength methods are applied to obtain reliable results for a wide selection of anisotropic and isotropic dipole properties of CO and for the dipole-dipole dispersion energy coefficients for the interaction of CO with CO, N 2 , H 2 , He, Ne, Ar, Kr and Xe. The properties of CO evaluated include the dipole oscillator strength sums S k , k = 2, 1, 0(− 1 2 ) −2, −3, −4, ⋯, the logarithmic dipole sums L k and mean excitation energies I k , k = 2(−1) −2, and, as a function of wavelength, the dynamic polarizability and its anisotropy, the total depolarization ratio, the Rayleigh scattering cross section, and the Verdet constant. Our constrained dipole oscillator strength results are often the only reliable, and sometimes the only, results available for many of the anisotropic dipole properties and dispersion energies considered in this paper.
