Isotropic dipole properties for acetone, acetaldehyde and formaldehyde

Abstract

Dipole oscillator strength distributions have been constructed for acetone, acetaldehyde and formaldehyde, by using constrained least-squares methods, experimental and mixture rule dipole oscillator strength data, and molar refractivity data. The distributions have been used to evaluate recommended values for a wide variety of isotropic dipole oscillator strength sums, logarithmic dipole sums, and mean excitation energies for each molecule. Often these results are the only (reliable) values available for many of these properties which are of importance in a variety of research areas.
