Abstract
A LARGE number of bands have been assigned1 to the molecule tellurium monoxide (TeO); but little agreement has yet been reached on their vibrational analysis, and no rotational analysis has yet been reported. By analogy with SeO (ref. 2), it is to be expected that the visible and near ultra-violet bands arise from a transition 3∑− – 3∑− in which the spin-splitting constants λ′ and λ″ are large. In the limit of case-c, the predicted 3∑− – 3∑− system will appear as two separate systems, 1 – 1 and 0+ – 0+. Some preliminary observations of the absorption spectrum taken in a second order of a 6.65-m concave grating spectrograph support this view.
