Quantum-ionic features in the absorption spectra of homonuclear diatomic molecules

A. Crawford-Uranga, D. J. Mowbray, D. M. Cardamone

We show that additional features can emerge in the linear absorption spectra of homonuclear diatomic molecules when the ions are described quantum mechanically. In particular, the widths and energies of the peaks in the optical spectra change with the initial configuration, mass, and charge of the molecule. We introduce a model that can describe these features and we provide a quantitative analysis of the resulting peak energy shifts and width broadenings as a function of the mass.
