EMISSION SPECTRUM OF A HIGH FREQUENCY DISCHARGE IN OXYGEN

Abstract

In a high frequency discharge through flowing oxygen at atmospheric pressure, it was possible, with high dispersing spectrographs, to extend the vibrational and rotational analysis of the Schumann-Runge bands (B 3 - X 3 system) up to 5 700 A. A predissociation at v' = 3 and 4 was observed; the v' = 4 level is strongly predissociated. It seems that there is no predissociation at v' = 5. In the same discharge we observe some new atmospheric bands. Each of the v = + 1 and v = 0 sequences have five bands. A suggestion is made that the excitation of the atmospheric bands is due to an interaction between the X 3 and b 1 states, enhanced at high pressure. (Author)
