The recently introduced "Feynman" dispersion correction for MNDO (MNDO-F) has been extended to include the elements fluorine, chlorine, bromine and iodine and the original parameterization for hydrogen, carbon, nitrogen and oxygen improved by allowing individual damping radii for the elements. MNDO-F gives a root-mean-square deviation to reference interaction energies of 0.35 kcal mol for the complete parameterization dataset of H, C, N, O, F, Cl, Br and I containing compounds. Graphical Abstract The electrostatic potential at the 0.001 a.u. isodensity surface of the π-complex between benzene and 1,3,5-triodobenzene calculated at the MNDO-F optimized geometry.
最近引入的用于MNDO的“费曼”色散校正（MNDO-F）已扩展到包括氟、氯、溴和碘元素，并且通过为这些元素设定单独的阻尼半径，改进了氢、碳、氮和氧的原始参数化。对于包含H、C、N、O、F、Cl、Br和I化合物的完整参数化数据集，MNDO-F给出的与参考相互作用能的均方根偏差为0.35 kcal/mol。图形摘要 在MNDO-F优化几何结构下计算得到的苯与1,3,5-三碘苯之间π络合物在0.001 a.u.等密度面上的静电势。
