Empirical corrections and pair interaction energies in the fragment molecular orbital method

Dmitri G. Fedorov, Jimmy C. Kromann, Jan H. Jensen

摘要:

结合Hartree-Fock方法和三个经验修正(HF-3c),得到了FMO的能量和解析梯度。将FMO的辅助基组方法推广到对相互作用能量分解分析。针对包括3种蛋白质的几种典型系统评价FMO准确度。对相互作用能计算与不同的方法在FMO进行了比较的水簇和蛋白质配体复合物。

英文摘要:

The energy and analytic gradient are developed for FMO combined with the Hartree-Fock method augmented with three empirical corrections (HF-3c). The auxiliary basis set approach to FMO is extended to perform pair interaction energy decomposition analysis. The FMO accuracy is evaluated for several typical systems including 3 proteins. Pair interaction energies computed with different approaches in FMO are compared for a water cluster and protein-ligand complexes.
