Infrared spectra of the matrix isolated OMS, OM(η2-SO), and OM(η2-SO)(η2-SO2) (M = Ti, Zr, Hf) molecules were observed following laser-ablated metal atom reactions with SO2 during condensation in solid argon and neon. The assignments for the major vibrational modes were confirmed by appropriate S18O2 and 34SO2 isotopic shifts, and density functional vibrational frequency calculations (B3LYP and BPW91)
基质分离OMS,OM(η的红外光谱2 -SO)和OM(η 2 -SO)(η 2 -SO 2)(M =钛,锆,铪)观察分子以下的激光烧蚀的金属原子反应在固体氩气和氖气中冷凝时,用SO 2与SO 2混合。通过适当的S 18 O 2和34 SO 2同位素位移以及密度函数振动频率计算(B3LYP和BPW91),确认了主要振动模式的分配。接合在初始OM(η 2 -SO)反应产物,并在OM(η 2 -SO)(η 2 -SO 2讨论了具有不寻常手性结构的加合物分子。
