Abstract : These studies are separated into two parts: one, the observed emission spectra in flowing gas streams in which the initiating energy source is an electrical discharge, and two, the study of properties of liquid and crystalline rare gases as affected by temperature and the addition of small quantities of impurities. Spectra obtained by the addition of atomic nitrogen to several volatile silicon compounds showed the best conditions for obtaining spectra of SiN and Si, and of several, as yet unidentified systems. The effect of discharge power on an extremely shorttime afterglow in nitrogen showed that it is possible to obtain, without serious overlapping from other band systems, relatively strong emission from three seldom observed N2 transitions known as the Goldstein-Kaplan bands, the Gaydon green system, and the Herman infrared bands. The condensed phase work consisted of learning new ways of growing crystalline rare gases and in looking for effects of laser interaction with condensed oxygen. (Author)
