Low-lying states of F2+

Abstract

Calculated potential energy curves for the 13 lowest electronic states of F₂ ⁺ are presented. Nine of the potential curves are found to possess substantial binding energies, while two others also display shallow, stable minima. The ordering, binding energies, relative equilibrium separations and vibrational frequencies of these curves should be of utility in helping to assign the large number of observed vibration-rotation lines in the electronic emission spectrum of F₂ ⁺. The calculated curves are in reasonable agreement with the available data on the two experimentally observed states.
