对S16O2和S18O2气体的近紫外吸收光谱进行了振动分析，结果表明，S16O2和S18O2的近紫外光吸收光谱为单电子跃迁，起始点为28238±50 cm−1(S18O2为28256±50 cm−1)。激发态基本为ν1‘=788 cm−1和ν2’=30 6 cm−1(S18O2为75 9 cm−1和2 93 cm−1)，并讨论了极弱起源的可能原因。
The near-ultraviolet absorption spectrum of S16O2and S18O2gas in the region 3000–3400 Å has been vibrationally analyzed as a single electronic transition with its origin at 28238 ± 50 cm−1(28256 ± 50 cm−1for S18O2). The excited statea1fundamentals areν1′ = 788 cm−1andν2′ = 306 cm−1(759 cm−1and 293 cm−1for S18O2), and possible causes for the extremely weak origin are discussed.
