Vibrational and rotational analysis of the near-infrared bands of S2 lying in the region 6983–7760Å are reported. They form a single progression of bands arising from a common vibrational level v'=0 of an initial 3Πgi state to levels v"= 0, 1, 2, and 3 of the final 3Πui state. The initial 3Πgi state is predissociated, as a result of which rotational levels with J'=34 of 3Π2g and J'≥16 of 3Π1g are not observed and, further, no transitions from the 3Π0g component are observed. These and other perturbations noticed in the different bands are discussed. The studies are also extended to the isotopic molecules 32S34S and 34S2.
