Summary
The ultra-violet bands of S2 reported first by Rosen and Desirant are studied under high resolution. The bands are excited in a microwave (2450 mc./s.) discharge through sulphur vapour containing34S in natural abundance and enriched to 44·4%. Rotational analysis of six bands at 2620, 2660, 2760, 2793, 2813 and 2847 Å shows that they involve a common1Δ u −1Δ g system. The observed vibrational and rotational constants are
