Analytical Division, Bombay, India. en_US dc.description Author Institution: Air Force Cambridge Research Laboratories., Geophysics Research Directorate en_US dc.description.abstract The investigation of the $\gamma$ and $\beta$ systems of NS molecule has been carried out in emission by using a Littrow type quartz spectrograph and a two meter normal incidence vacuum spectrograph. Nitrogen was flowed continuously through a discharge tube containing sulphur. The tube was heated in such a way as to give the maximum intensity of the NS bands and to avoid the appearence of sulphur and nitrogen bands. The $\gamma$ system $(^{2}\Sigma-{^{2}}\Pi)$, in which only the bands having $v^{\prime}=0$ were known previously, has been extended to $v^{\prime}=4$, thus giving the vibrational constants for the upper state. The bands with $v^{\prime}=2, 3$ and 4 show some irregularity indicating perturbation in the upper state. The $\beta$ system ($^{2}\Delta-{^{2}}\Pi$) has also been extended. The constants for the $^{2}\Delta_{**} ^{2}\Pi_{**}$ transition have been slightly modified. Four new systems have been observed in the ultraviolet and in the vacuum ultraviolet regions. The details of the vibrational analysis for the $\gamma$ and $\beta$ systems along with some discussion regarding the new systems will be presented in the paper. en_US dc.format.extent 140642 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.title THE EMISSION SPECTRUM OF NS MOLECULE en_US dc.type article en_US
