What Does PCI Stand For?
PCI stands for Perturbative Configuration Interaction
Perturbative Configuration Interaction (PCI) is a quantum chemistry method used to improve the accuracy of wavefunction calculations for molecular systems. It builds upon configuration interaction (CI) by incorporating perturbative corrections to account for electron correlation effects, enabling a more precise description of electronic states. PCI is particularly useful in scenarios where full CI is computationally prohibitive, allowing for enhanced predictive capabilities in the study of molecular properties and reactions.
