Effect of the avoided crossing on the rovibrational energy levels, resonances, and predissociation lifetimes within the ground and first excited electronic states of lithium fluoride

V. G. Ushakov, A. Yu. Ermilov, E. S. Medvedev

We investigate the LiF spectrum up to $7800$ cm${}^{-1}$ above the first dissociation limit. The ab initio calculations of the adiabatic potentials and other molecular functions are…
