What Does PEMC Stand For?

PEMC stands for Pair Excitation Multiconfiguration Type Of Wave Function

PEMC, or Pair Excitation Multiconfiguration Type Of Wave Function, is a computational method used in quantum chemistry and theoretical physics. It combines multiple configuration interactions with pair excitation techniques to accurately describe electronic states of molecular systems. By focusing on pairwise excitations, PEMC enhances the ability to capture electron correlation effects, leading to improved predictions of molecular properties and behaviors in complex systems. This method is particularly useful for studying excited states and transition phenomena in various chemical environments.
