Quantum Chemistry Computer Codes 1. “POLYMER 1.0,” S. Hirata, M. Tasumi, H. Torii, S. Iwata, M. Head-Gordon, and R. J. Bartlett, (1999). A first-principles quantum chemistry computer program for infinite one-dimensional lattices (polymers). The ground-state energies (Hartree–Fock theory, density functional theory, second- and third-order many-body perturbation theory, and coupled-cluster theory), optimized geometries (analytical gradient method), vibrational frequencies, quasi-particle energies (second-order many-body perturbation theory and Green’s function theory), excited-state energies (configuration interaction singles theory, time-dependent Hartree–Fock theory, and time-dependent density functional theory) can be calculated for polymers. For atoms and molecules, full configuration interaction calculations, high-order determinantal many-body perturbation calculations, high-order determinantal coupled-cluster calculations, high-order determinantal equation-of-motion coupled-cluster calculations, and optimized effective potential calculations can be performed. 2. “Q-CHEM 2.0,” J.
