The ( 5 ) Σ 1 g + state has been studied by two-step excitation spectroscopy. 270 levels in the state were measured with high resolution. A set of Dunham coefficients was deduced to fit all levels with v < 19. The spectroscopic data were used to construct a Rydberg–Klein–Rees potential for the state. The potential shows that the state is perturbed by other Rydberg states and ionic states and seems likely to have a second well that is due to avoided crossings with these states.
