测量了邻碳硼烷、间碳硼烷、对碳硼烷以及各种碳和硼取代的邻碳硼烷的碳氢偶合常数(J(13 C-1H))。这些值聚集在190 Hz附近,这意味着CH键中约有38%的s特征,或大约为sp1*· 6的杂化。
Carbon-hydrogen coupling constants (J (13C-1H)) are measured for o-carborane, m-carborane, p-carborane, and various carbon-and boron-substituted o-carboranes. The values cluster about 190 Hz, implying approximately 38% s character in the CH bond, or a hybridization of roughly sp1*· 6.
