RESEARCH USE
Where PySCF fits
Define the molecular or periodic system, basis, electronic state, and method explicitly in Python, then combine self-consistent-field, density-functional, correlated, and property modules into a reproducible calculation. Preserve geometry and units, charge and spin, basis and pseudopotentials, convergence thresholds, numerical grids, software and extension versions, and complete input and output. Test convergence and sensitivity to the chosen method.
Research tasks
- Calculate electronic structure for molecules or periodic systems
- Develop and test quantum-chemistry methods
- Embed electronic-structure calculations in automated research workflows
What to evaluate before use
- Numerical convergence does not establish that the physical model is adequate. Results depend on the method, basis, pseudopotential, relativistic treatment, charge, and spin specification.
- Large or multireference systems can fall outside common single-reference assumptions. Consequential results need comparison with higher-level methods, experiment, or an independent implementation.
