What Does CCI Stand For?
CCI stands for Complete Configuration Interaction
Complete Configuration Interaction (CCI) is a comprehensive quantum chemistry method used to calculate the electronic structure of molecules. It involves the exact diagonalization of the Hamiltonian operator in a complete basis of many-electron configurations, allowing for accurate predictions of molecular energies and properties. CCI is particularly valuable in systems where electron correlation plays a significant role, providing insights into chemical reactions and molecular behavior at a high level of precision. Due to its computational intensity, CCI is typically applied to smaller systems or utilized in conjunction with other quantum methods to enhance efficiency.
