PySCF Quantum Chemistry Purpose Provides expert guidance on PySCF quantum chemistry calculations, including post-Hartree-Fock methods and multireference approaches. Capabilities - Hartree-Fock and post-HF methods - Coupled cluster (CCSD, CCSD(T)) - CASSCF/CASPT2 multireference - Periodic boundary conditions - Relativistic corrections - DMRG integration Usage Guidelines 1. System Setup : Define molecular geometry and basis set 2. Mean-Field : Run Hartree-Fock calculations 3. Correlation : Apply post-HF methods for correlation 4. Multireference : Use CASSCF for strongly correlated systems 5. Ad…
