What Does FCI Stand For?

FCI stands for Full Configuration Interaction

FCI, or Full Configuration Interaction, is a computational method used in quantum chemistry to solve the Schrödinger equation for complex molecular systems. It involves considering all possible electronic configurations and their corresponding wavefunctions, providing an exact solution to the electronic structure problem. FCI is computationally intensive and generally applied to small molecules or systems where high accuracy is essential, serving as a benchmark for other approximate methods in electronic structure calculations.
