Abstract
The Woods band at 3840AA and the SiN bands in the region 3900-4900AA (A2 Sigma -X2 Sigma transition) have been excited strongly under well controlled conditions in a high frequency discharge. From the results of the present studies it has been shown that the emitter of the Woods band at 3840 AA is SiO+ and not SiN. A critical review of the data, used by Nagaraj and Verma (1968) to attribute the Woods band to B2 Sigma -A2 Sigma transition of SiN, supports our assignment of the Woods band to SiO+. The intensity behaviour of the SiN bands (3900-4900 AA) excited in the high frequency discharge and in the afterglow of nitrogen has also been described.Keywords
