Several Rydberg series attributable to transitions originating from the a 3Σ+u metastable state of the neon dimer have been observed by laser excitation spectroscopy in the afterglow of a pulsed corona discharge. The n = 4-9 members of an npπ Πg←a(0-0) series have been rotationally resolved and the upper states characterized. The probable multiplicity of the Πg states is discussed. An unusual loss of intensity in the Q branches for the higher n member transitions and a weak perturbation between the υ= 1 vibrational level of the 5fσ 3Σ+g state and the 6pπ Πg, υ=0 level are also reported.
