Machine learningPost-Hartree-Fock Method

Coupled Cluster CCSD

Teorija sprege klastera (Coupled Cluster theory), osobito CCSD (Singles and Doubles) i CCSD(T) s perturbacijskim trostrukim pobuđenjima, jedna je od najtočnijih metoda za elektronsku strukturu molekula. Razvijena od strane Jiri Cizeka 1966. godine, CC teorija tretira valnu funkciju osnovnog stanja kao eksponencijalu operatora pobuđenja primijenjenih na Hartree-Fock referencu, omogućujući sustavno tretiranje elektronske korelacije uz zajamčenu dosljednost veličine.
