TL;DR

This paper compares how static electric fields influence the rovibrational spectra of various polar heteronuclear alkali dimers, analyzing energy shifts, orientation, and hybridization effects near dissociation.

Contribution

It provides a detailed comparative analysis of electric field effects on rovibrational properties of multiple heteronuclear alkali dimers in their ground state.

Findings

Electric fields cause measurable energy shifts in rovibrational spectra.

Field-induced orientation and alignment vary with vibrational excitation.

Hybridization of angular motion increases near dissociation threshold.

Abstract

A comparative study of the effect of a static homogeneous electric field on the rovibrational spectra of several polar dimers in their $\textrm{X}^1\Sigma^+$ 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.
