在2069.3 cm-1处观察到一个新的红外波段,并将其分配给长期预期的OCS二聚体的极性异构体,这有助于解释早期研究之间的明显差异。这里报告的数据应该能够直接观察极性(OCS)2的微波光谱,并激发新的理论工作的OCS二聚体异构体的能量和相互转换的能量障碍。
A new infrared band at 2069.3 cm-1 is observed and assigned to the long-anticipated polar isomer of the OCS dimer, helping to explain apparent discrepancies among earlier studies. The data reported here should enable direct observation of the microwave spectrum of polar (OCS)2 and motivate new theoretical works on the energetics of OCS dimer isomers and interconversion energy barriers.
