Collision-induced energy transfer in the B 3Σu− state of diatomic sulfur

Rates for collision-induced vibrational and rotational energy transfer within the B 3Σu− state of diatomic sulfur are reported. The S2 was initially excited to v′=4, N′=40, J′=41 by absorption of a Zn atomic line. Fluorescence measurements, made as a function of foreign gas pressure, were used to determine the rates. The collision partners investigated were the five rare gases, H2, and N2. In addition, the rate of quenching of S2 (B, v′=4) by S2 (X) is reported.
