| Abstract: | High dispersion spectrograms of NiCl, in the photographic infrared (λ6350?λ8750Å) have shown the existence of five new band systems, designated as F, G, H, I and J. The bands in all the five systems are degraded to longer wavelengths. The F, G and I systems consist of single headed bands while H and J systems consist of double headed bands. Approximate vibrational constants have been determined from the vibrational analysis. The observed structure of the bands indicates doublet-doublet transitions, as in the visible band systems of NiCl. |
