What Does CI Stand For?

CI stands for Configuration Interaction

Configuration Interaction (CI) is a computational quantum chemistry method used to describe the electronic structure of many-body systems. By considering multiple electronic configurations, CI accounts for electron correlation effects more accurately than single-reference approaches. This method involves creating a linear combination of various electronic configurations, allowing for a more precise calculation of energy levels and properties of molecules, thereby enhancing the understanding of chemical behavior and reactivity. CI is particularly valuable in predicting spectroscopic properties and in studying excited states.
