Rotational Analysis of the Tantalum Oxide Bands

THE bands of tantalum oxide have been photographed in the second order of a 21-ft. concave grating having 30,000 lines per inch and giving a dispersion of 0.6 A./mm. Rotational structure of three of these bands, λ 3,747 (ν 26,679), λ 4,155 (ν 24,063) and λ 4,282 (ν 23,348), has been analysed; the first of these is the (0,0) head of one system and the other two are the (1,0) and (0,0) heads of another system of TaO1. The analysis indicates that (1) the three bands have a common ∑ ground-state which is probably a doublet, (2) ν 26,679 results from a transition between two doublet ∑ states, and (3) ν 23,348 and ν 24,063 are attributed to the transition 2π − 2∑.
