Analysis and synthesis have been performed on portions of unpublished ground-based nightglow spectra taken at ~0.5 ¿ resolution by A. L. Broadfoot in 1968. The bands of the three O2 systems radiating in the 3400- to 3800-¿ region are rotationally resolved, and lines from three different c1∑-u→X3∑-g bands, the system that dominates the visible Venusian nightglow, are clearly identified.
