我们开发了一种用于与单链相互作用的微扰双校正的并行积分-直接程序,由Head-Gordon等人提出为CIS(D)。(Chem Phys Lett 219:21,1994)。CIS(D)方法为相应的CIS激发态提供了弛豫关联和微分关联的能量修正。CIS(D)的实现是基于我们最初的二阶Møller-Plesset摄动(MP2)计算算法(Mochizuki等人)。摘自《Theor Chem Acc112:442,2004》)。不需要在并行执行的工作进程之间传递庞大的中间数据。然后将该CIS(D)程序并入开发版本的ABINIT-MP程序中,以改善由CIS方法结合多层碎片分子轨道方案(MLFMO-CIS)(Mochizuki等人)计算的激发能的高估。收录于《化学物理》,Lett 406:283,2005)。首次用MLFMO-CIS(D)方法计算了水合甲醛的最低激发能npi。光活性黄蛋白(PYP)是MLFMO-CIS(D)计算的第二个靶点。通过这些应用表明,CIS(D)校正可以很好地改善CIS的结果。
We have developed a parallelized integral-direct code of the perturbative doubles correction for configuration interaction with singles, proposed as CIS(D) by Head-Gordon et al. (Chem Phys Lett 219:21, 1994). The CIS(D) method provides the energy corrections both of the relaxation and differential correlation for the respective CIS excited states. The implementation of CIS(D) is based on our original algorithm for the second-order Møller–Plesset perturbation (MP2) calculations (Mochizuki et al. in Theor Chem Acc 112:442, 2004). There is no need to communicate bulky intermediate data among worker processes of the parallelized execution. This CIS(D) code is then incorporated into a developer version of ABINIT-MP program, in order to improve the overestimation in excitation energies calculated by the CIS method in conjunction with the multilayer fragment molecular orbital scheme (MLFMO-CIS) (Mochizuki et al. in Chem Phys Lett 406:283, 2005). The MLFMO-CIS(D) method is first used in evaluating the lowest n$$pi^{*}$$ excitation energy of the hydrated formaldehyde. The photoactive yellow protein (PYP) is the second target of MLFMO-CIS(D) calculation. Through these applications, it is shown that the CIS(D) correction improves the CIS results favorably.
