在过去的几十年里,计算化学领域已经成功地表现出自己作为一个关键的补充,以更传统的实验室为导向的化学。这是特别真实的,在最近复兴的全组态相互作用(FCI)水平的方法,虽然只有当这些可以证明自己足够强大和通用的常规应用到各种感兴趣的化学问题。在目前的一系列工作中,性能和功能增强的一个这样的途径,对FCI水平的结果,为中等到大的单电子基组,最近推出的多体扩展全组态相互作用(MBE-FCI)形式主义[J.物理化学快报。2017年8月,4633 ],将提交。具体来说,在这个系列的开放部分,MBE-FCI方法在生产近精确的基态能量的弱相关分子的任何自旋多重性的能力将被证明。
Over the course of the past few decades, the field of computational chemistry has managed to manifest itself as a key complement to more traditional lab-oriented chemistry. This is particularly true in the wake of the recent renaissance of full configuration interaction (FCI)-level methodologies, albeit only if these can prove themselves sufficiently robust and versatile to be routinely applied to a variety of chemical problems of interest. In the present series of works, performance and feature enhancements of one such avenue toward FCI-level results for medium to large one-electron basis sets, the recently introduced many-body expanded full configuration interaction (MBE-FCI) formalism [ J. Phys. Chem. Lett. 2017 , 8 , 4633 ], will be presented. Specifically, in this opening part of the series, the capabilities of the MBE-FCI method in producing near-exact ground state energies for weakly correlated molecules of any spin multiplicity will be demonstrated.
