What Does PERTCI Stand For?

PERTCI stands for Perturbational Configuration Interaction

PERTCI, or Perturbational Configuration Interaction, is a theoretical framework used in quantum chemistry and computational physics to study the electronic structure of molecular systems. It combines perturbation theory with configuration interaction methods to improve the accuracy of electronic energy calculations and wavefunction descriptions. By systematically incorporating the effects of electronic correlation, PERTCI enables more precise modeling of complex molecular interactions and facilitates the exploration of excited states, reaction dynamics, and other phenomena in various chemical systems.
