| single-point HF/qz2p on water | |
| single-point CCSDT/qz2p on NH2 | |
| single-point CCSD(T)/qz2p on water with ecc, aobasis, and frozen-core | |
| Basis set spherical/Cartesian with cfour_basis and cfour_spherical | |
| MP2 optimization of dimers with one momomer ghosted. Gradients after three opt cycles are compared with those from psi4. | |
| single-point CCSDT/qz2p on water | |
| single-point CCSD(T)/qz2p on NH2 with ecc, aobasis | |
| RHF cc-pVDZ energy for water, automatically scanning the symmetric stretch and bending coordinates using Python’s built-in loop mechanisms. The geometry is apecified using a Z-matrix with variables that are updated during the potential energy surface scan, and then the same procedure is performed using polar coordinates, converted to Cartesian coordinates. | |
| Basis set spherical/Cartesian with basis and puream | |
| single-point HF/qz2p on NH2 | |
| single-point CCSDT/qz2p on NH2 | |
| geometries from a variety of input formats. references from psi4, testing whether geometry strings read identically for psi4/cfour | |
| optimization CCSD(T)/dzp on water | |
| SAPT calculation on bimolecular complex where monomers are unspecified so driver auto-fragments it. Basis set and auxiliary basis sets are assigned by atom type. | |
| ROHF MP2 energy components. Checks that computed identically between cfour and psi4 | |
| Basis set spherical/Cartesian with basis and cfour_spherical | |
| testing best practices options, part ii | |
| single-point HF/qz2p on NH2 | |
| single-point CC3/qz2p on water | |
| MP2 energy components. Checks that computed identically between cfour and psi4 | |
| UHF MP2 energy components. Checks that computed identically between cfour and psi4 | |
| single-point CC3/qz2p on NH2 | |
| single-point CCSD/qz2p on NH2 | |
| single-point CCSD(T)/qz2p on water | |
| MP2/cc-PVDZ computation of formic acid dimer binding energy using automatic counterpoise correction. Monomers are specified using Cartesian coordinates. | |

| UHF MP3 energy components. Checks that converted identically between cfour and psi4 | |
| single-point CCSD(T)/qz2p on water with ecc module | |
| single-point MP2/qz2p on water | |
| single-point CCSD(T)/qc2p on water with ecc, aobasis | |
| single-point CCSD(T)/qz2p | |
| Various basis set extrapolation tests only in Cfour instead of Psi4 | |
| geometry after three optimization cycles for a variety of input formats, references from psi4 | |
| single-point MP2/qz2p on NH2 | |
| MP3 energy components. Checks that computed identically between cfour and psi4 | |
| single-point CCSD(T)/qz2p on NH2 with ecc | |
| single-point CCSD(T)/qz2p on NH2 with ecc, aobasis | |
| single point CCSD/qz2p on water | |
| Translating psi4 options to cfour, part ii | |
| single-point CCSD(T)/qz2p on NH2 with ecc, aobasis, frozen-core | |
| optimization HF/svp on water | |
| single-point CCSD/qz2p on water with aobasis | |
| single-point MP4/qz2p on NH2 | |
| Basis set spherical/Cartesian behavior in cfour | |
| Database calculation, so no molecule section in input file. Portions of the full databases, restricted by subset keyword, are computed by sapt0 and dfmp2 methods. | |
| single-point CCSD(T)/qz2p on water with aobasis | |
| Translating psi4 options to cfour, part i | |
| single-point CCSD(T)/qz2p on NH2 | |
