What Does CPFD Stand For?

CPFD stands for Coupled Pair Functional With Double Excitation

CPFD, or Coupled Pair Functional With Double Excitation, is an advanced computational chemistry method that enhances the accuracy of electronic structure calculations. It combines features of coupled cluster theory with pairwise correlation approaches, effectively accounting for electron correlation effects through double excitation. This method facilitates the investigation of molecular systems by providing reliable energy and property predictions, making it a valuable tool for researchers in theoretical and computational chemistry.
