methods, while its epimer anti-7-norbornenol (2) has been investigated by theoretical methods only. It was found that 1 is intramolecularly hydrogen bonded and exists almost exclusively in its hydrogen bonded form, the Anti conformer. Compound 2, for which intramolecular hydrogen bonding is impossible, was found to exist as the Gauche conformer. A theoretical investigation of the model complex between methanol
摘要 用理论和实验方法研究了syn-7-norbornenol (1) 的几何结构和能量,而仅用理论方法研究了其差向异构体anti-7-norbornenol (2)。发现 1 是分子内氢键,并且几乎完全以其氢键形式存在,即反构象异构体。发现分子内氢键不可能形成的化合物 2 作为 Gauche 构象异构体存在。

乙烯之间的模型复合物的理论研究表明,相互作用能为 -3.1±0.1 kcal mol-1(估计的 Hartree-Fock 基组限制加上相关贡献,不包括振动零点能量)。电子相关性对于评估相互作用能以及复合物的几何形状至关重要。
