Intensity Measurements on the Nitrogen Second Positive System in a Low Temperature Discharge

Abstract

Integrated band intensities of the second positive system (C3II-B3II) of N2 have been measured photoelectrically. They have been used to test the range of conditions under which the theory normally used in interpreting such measurements is applicable. They have also been used in a new determination of the variation of the electronic transition moment with internuclear separation. The variation of the population of the C3II state with current has been determined and used to identify the probable excitation processes.
