Abstract

A technique has been devised to measure the temperature of discharge excited diatomic sulfur. The band-shape of the transition from the υ′ = 8 level in the B³Σ⁻ electronic state of the υ″ = 0 level in the X³Σ⁻ state is due to unresolved rotational structure. The observed bandshape was compared to the results of a computer simulation that used the line strength factors of Tatum and Watson for spin-rotation coupling intermediate between Hund’s cases (a) and (b).
