pi-pi Interaction in pyridine dimer and trimer has been investigated in different geometries and orientations at the ab initio (HF, MP2) and DFT (B3LYP) levels of theory using various basis sets (6-31G, 6-31G, 6-311++G) and corrected for basis set superposition error (BSSE). While ...
The maximum electrostatic potential of organocations computed with density functional theory was found to be a strong predictor of the pi(+)-pi EDA interaction. The pi(+)-pi EDA interaction was disfavored by electropositive alkyl substituents and by charge delocalization into additional rings. ...

摘要: The pi-pi interaction amplitudes have been calculated using a three coupled channel model both with and without constraints imposed by chiral models. Roy's equations have been used to compare the amplitudes and to study the role played by chiral constraints in the pi-pi interaction....

The sulfur-pi interaction is then studied by using the hydrogen sufide-benzene dimer as a prototype system for theoretical predictions. We obtain higly-accurate potential energy curves, as well as an interaction energy extrapolated to the complete basis set limit. Energy decomposition analysis using ...
阳离子-π相互作用是富电子π系统(例如苯,乙烯,乙炔)和相邻阳离子(例如Li +,Na +)之间的非共价分子相互作用。 这种相互作用是单极(阳离子)和四极(π系统)之间非共价键的一个例子。 结合能非常重要,固溶相值(solution-phase values)与氢键和盐桥在同一数量级内。 与这些其他非共价键相似,阳离子-π相互作用在自...
