Comparative study of the rovibrational properties of heteronuclear alkali dimers in electric fields

Abstract

A comparative study of the effect of a static homogeneous electric field on the rovibrational spectra of several polar dimers in their ${\text{X}}^1{\Sigma }^{+}$ electronic ground state is performed. Focusing upon the rotational ground state within each vibrational band, results for energies and various expectation values are presented. For moderate field strengths the electric field-induced energy shifts, orientation, alignment, and angular motion hybridization are analyzed up to high vibrational excitations close to the dissociation threshold.
