Abstract
OXYGEN produced by heating potassium permanganate crystals was excited by a high-frequency (750–850 kc./sec.) discharge (output power less than 10 watts) and the spectra protographed both in the visible and in the ultra-violet regions by a Fuess glass prism spectrograph and a small (baby) quartz prism spectrograph respectively. A good many of the more intense bands of the Schumann-Runge system were found on both our plates. On attempting to extend the system, we discovered that a number of new bands present on our plates, but not reported by previous workers, fitted in the (v'v") scheme of this system. These new bands (vvac) along with our proposed quantum assignments are given in the accompanying table.
