What is the basic idea behind Coupled Cluster Theory?
AnswerClick to flip back
A
It is a variational method that uses a wave function that is a linear combination of Slater determinants.
💡 Explanation:
Coupled Cluster Theory is a variational method, meaning that it seeks to find the lowest energy wave function that satisfies the Schrödinger equation. The wave function used in Coupled Cluster Theory is a linear combination of Slater determinants, which are antisymmetrized products of one-electron orbitals.
