摘要： 采用密度泛函理论, 在B3LYP/6-311++G(d, p)水平上对以吡咯为质子供体的一系列双氢键体系进行了详细的研究. 采用AIM理论对双氢键体系进行了电子密度拓扑分析, 讨论了双氢键的成键特征和双氢键形成前后受体和供体H原子的积分净电荷、偶极矩、体积和能量的变化.

关键词: 双氢键, 电子密度, 拓扑分析, 吡咯, 原子积分性质

Abstract: Dihydrogen-bonded complexes formed from pyrrole and a series of small molecules were studied at density functional B3LYP/6-311++G(d, p) level of theory. The topological characters of the electron density and atomic integral characters of the dihydrogen-bonded complexes were investigated extensively. Especially, the changes of atomic net charge, dipole moment, energy and volume of both the proton-donors and acceptors in the forming process of dihydrogen-bond were discussed.

Key words: Dihydrogen bond, Electron density, Topological analysis, Pyrrole, Atomic integral character
