Kvantum kemisk programpakke

PSI4 er et ab-initio kvantekemiprogram. Det er specielt designet til nøjagtigt at beregne egenskaber for små til mellemstore molekyler ved hjælp af højt korrelerede teknikker. PSI4 er den parallelle efterfølger til PSI3 og indeholder mange moderne teoretiske metoder.

It can compute energies, gradients and hessians for the following methods:

 * Restricted Hartree-Fock (RHF)

It can compute energies and gradients for the following methods:

 * Restricted, unrestricted and general restricted open shell Hartree-Fock
   (RHF/ROHF)
 * Restricted, unrestricted and general restricted open shell
   Densitry-Functional Theory, including density-fitting (DF-DFT)
 * Density Cumulant Functional Theory (DCFT)
 * Density-fitted Moeller-Plesset perturbation theory (DF-MP2)
 * Density-fitted Orbital-Optimized MP2 theory (DF-OMP2)
 * (Orbital-Optimized) MP3 theory (OMP3/MP3)
 * Coupled-cluster singles doubles (CCSD)
 * Density-fitted coupled-cluster singles doubles (DF-CCSD) and with
   perturbative triples (DF-CCSD(T))
 * Second-order approximate coupled-cluster singles doubles (CC2)
 * Equation-of-motion coupled-cluster singles doubles (EOM-CCSD)

Additionally, it can compute energies for the following methods:

 * Spin-component scaled MP2 theory (SCS-MP2)
 * Fourth order Moeller-Plesset perturbation theory (MP4)
 * Density-fitted symmetry-adapted perturbation theory (DF-SAPT)
 * Density-fitted complete active space SCF (DF-CASSCF)
 * Configuration-interaction singles doubles (CISD)
 * Full configuration-interaction (FCI)
 * Closed-shell Density-fitted coupled-cluster singles doubles (DF-CCSD)
 * Closed-shell Density-fitted Coupled-cluster singles doubles with
   perturbative triples (DF-CCSD(T))
 * Second/third-order approximate coupled-cluster singles doubles (CC2/CC3)
 * Mukherjee Multireference coupled-cluster singles doubles theory (mk-MRCCSD)
 * Mukherjee Multireference coupled-cluster singles doubles with perturbative
   triples theory (mk-MRCCSD(T))
 * Second order algebraic-diagrammatic construction theory (ADC(2))
 * Quadratic configuration interaction singles doubles (QCISD)
 * Quadratic configuration interaction singles doubles with perturbative
   triples (QCISD(T))
 * Density Matrix Renormalization Group SCF (DMRG-SCF), CASPT2 (DMRG-CASPT2)
   and CI (DMRG-CI)

Further features include:

 * Flexible, modular and customizable input format via Python
 * Excited state calculations with the EOM-CC2/CC3, EOM-CCSD, ADC(2), MRCI and
   mk-MRCC methods
 * Utilization of molecular point-group symmetry to increase efficiency
 * Internal coordinate geometry optimizer
 * Harmonic frequencies calculations (via finite differences)
 * Potential surface scans
 * Counterpoise correction
 * One-electron properties like dipole/quadrupole moments, transition dipole
   moments, natural orbitals occupations or electrostatic potential
 * Composite methods like complete basis set extrapolation or G2/G3
 * Scalar-relativistic corrections via two-component approach (X2C)
