What Does CCDPPA Stand For?

CCDPPA stands for Coupled Cluster With Double Excitation Polarization Propagator

CCDPPA, or Coupled Cluster With Double Excitation Polarization Propagator, is an advanced computational method used in quantum chemistry. It combines the coupled cluster approach, which accounts for electron correlation through multi-reference excitations, with a polarization propagator framework that enables the accurate modeling of electronic excitations and response properties. This technique is particularly effective in studying molecular systems where electron correlations play a significant role, thus allowing for improved predictions of spectral properties and reactivity in various chemical environments.
