The molecular geometries, the proton isotropic hyperfine coupling constants (hfcc) of SO -_2 and SO -_3, and the adiabatic electron affinities (AEAs) of the corresponding neutral molecules have been studied by performinig the quadratic CI calculations including single and double substitutions (QCISD) with the 6-311G(d), 6-311+G(d), 6-311G(2d) and 6-311+G(2d) basis sets.

使用二次组态相互作用(QCISD)方法和 6 3 11G(d),6 3 11+G(d),6 3 11G(2d)及 6 3 11+G(2d)基组研究了SO-2 和SO-3的分子结构,超精细偶合常数(hfcc)及其对应的分子的绝热电子亲合势(AEA)。

The laser-induced fluorescence excitation spectrum of jet-cooled NS and SO radicals has been investigated.

同时实验测定了SO在34000-43000cm-1范围内的激光诱导荧光激发谱,将其归属为SO自由基的B3Σ--X3Σ-跃迁,并测量了B态部分振转能级的荧光辐射寿命。
