Band Spectrum of Antimony Monoxide (SbO)

The present paper reports the vibrational structure analysis of the emission band spectrum of the diatomic molecule, SbO, in the region λ3200-λ6800. The bands have been assigned to two system designated as the more refiangible and the less refiangible systems of the molecule and arc due respectively to 2 Σ → 2∏and 2∏→ 2 ∏ and transitions.They have a common lower state which shows a separation of 2272cm-1, between Π-components. From analogy with the other members of the group V(b) oxides, this common lower state seems in all probability to be the ground state of the molecule in question
