| Abstract: | Two series of emission bands were observed for the CS2/Ar(1 : 100–500) system at 15 K with excitation at 257.3 nm. They are assigned to B3Σ?u → χ3Σ?g and B″3Πu → X3Σ?g of S2, which was formed by photodissociation of CS2, CS2 + hv → CS + S, followed by recombination of two S atoms. The B″3Πu state has been found 524 cm-1 lower in energy than B3Σ?u |
