sulfur atoms S (P 2, 1, 0 3) and S (D 2 1) resulting from the 193.3 nm photodissociation of CS
2 have been measured using tunable vacuum ultraviolet (vuv) laser radiation in the
frequency range of 82 750–83 570 cm− 1. The PIE spectrum of S (P 2, 1, 0 3) near their
ionization threshold exhibits steplike structures. On the basis of the velocity-mapped ion-
imaging measurements, four strong autoionizing peaks observed in the PIE measurement in …
