Observational data and theoretical models of nightglow emissions from atomic and molecular oxygen in the atmospheres of the earth, Mars, and Venus are reviewed. It is proposed that the states responsible for several nightglow components are excited indirectly from the c1Sigma state of O2: O2 (c1Sigma) + O yields O2 + O (1S) with emission at 557.7 nm; O2 (c1Sigma) + O yields O2 (a1Delta) + O with emission at 1.27 microns; and O2 (c1Sigma) + O2 yields O2 + O2 (b1Sigma) with emission at 761.9 nm. The need for further detailed observations of planetary nightglow, for more refined laboratory measurements of the kinetics of the processes involved, and for a spectroscopic explanation for the preferential production of the c1Sigma state in the recombination of atomic oxygen is indicated.
