The molecular structure of 1,2-bis(trifluoromethyl)-1,1,2,2-tetramethyldisilane has been determined in three different phases (solid, liquid, and gas) using various spectroscopic and diffraction techniques. Both the solid-state and gas-phase investigations revealed only one conformer to be present in the sample analyzed, whereas the liquid phase revealed the presence of three conformers. The data have
1,3-双(三氟甲基)-1,1,2,2-四甲基乙硅烷的分子结构已使用各种光谱和衍射技术在三个不同的相(固相,液相和气相)中确定。固态和气相研究均表明在所分析的样品中仅存在一种构象异构体,而液相则表明存在三种构象异构体。数据已使用计算方法重现,并提出了用于观察液态三个构象异构体的原理。
