Journal ArticleDOI
A linear response, coupled‐cluster theory for excitation energy
Hideo Sekino,Rodney J. Bartlett +1 more
TL;DR: In this paper, expressions for static and dynamic properties in coupled-cluster (CC) theory are derived using diagrammatic techniques and shown how consideration of orbital relaxation effects in the theory introduces higher-order correlation effects.
Journal ArticleDOI
Comparison of MBPT and coupled-cluster methods with full CI. Importance of triplet excitation and infinite summations☆
TL;DR: In this article, the results from full fourth-order perturbation theory (SDTQ MBPT) and coupled-cluster single and double-excitation model (CCSD) were compared with recent full CI results for BH, HF, NH3, and H2O.
Journal ArticleDOI
Multiplicity of many-body wavefunctions using unrestricted Hartree-Fock reference functions
Journal ArticleDOI
Frequency-dependent hyperpolarizabilities in the coupled-cluster method: the Kerr effect for molecules
Hideo Sekino,Rodney J. Bartlett +1 more
TL;DR: In this paper, the frequency dependence in the equation-of-motion coupled-cluster method was introduced to evaluate the optical Kerr effect for butadiene and ammonia, and a critical evaluation of dispersion estimates via the uncorrelated time-dependent Hartree-Fock theory was performed.
Journal ArticleDOI
Nuclear coupling constants obtained by the equation-of-motion coupled cluster theory
Hideo Sekino,Rodney J. Bartlett +1 more
TL;DR: In this paper, a generalized sum over state formulation based upon the equation of motion CC intermediate state wavefunctions was applied to calculate the Fermi contact contribution to the indirect spin-spin coupling constants (J) of several molecules; ethane, cyclopropane and cyclobutane, bicyclobutanes, ethylene and hydrogen fluoride.
