Chapter 5, Problem 5.6P

High-resolution photoelectron spectroscopy has provided information on the energy levelsand bond distance in the ion ${\text{Ar}}_{{\text{2}}^{+}}$ Prepare a molecular orbital energy-level diagram for this ion.How would you expect the bond distance in ${\text{Ar}}_{{\text{2}}^{+}}$ to compare with 198.8 pm, the bond distance in ${\text{cl}}_{\text{2}}$ (See A. Wüst, F. Merkt, J. Chem. Phys., 2004, 120, 638.)
