The spectrum of an electrodeless discharge in pure oxygen has been studied. New bands of the O2+ Second Negative system have been found and the intensity distribution in this system is discussed; subsidiary parabolae as well as the main Franck-Condon parabola are obtained as is predicted by the theory. Emission bands reported by Johnson as due to O3 are due to O2+ and O II. Some abnormal intensities of O II lines excited in the electrodeless discharge are noted. The electrostatic and electromagnetic types of excitation are briefly compared.
