Spectra of the collision-induced emission from S(1S)

Abstract
The spectra of collision‐induced emission from S(1S) in collisions with He, Ar, N2, H2, Kr, and Xe have been measured. The S(1S) was made by OCS photodissociation with both a xenon resonance lamp (1470 Å) and a CO 4+ lamp (1500–1600 Å). With all gases except xenon, the most obvious effect on the S(1S03P1) transition at 4590 Å is the appearance of a neighboring ’’line’’ at 4508 Å corresponding to the S(1S03P2) transition. No evidence of the S(1S03P0) transition at 4628 Å is seen. Xenon does not produce the 4508 Å emission but results in the appearance of a blue degraded band extending from the 4590 Å line. All of the gases produce a blue degraded band on the S(1S01D2) transition at 7727 Å. The implications of these results for the potential curves of XeS are discussed.
