What Does CISDT Stand For?

CISDT stands for CI With Single And Double And Triple Excitations

CISDT, or CI With Single And Double And Triple Excitations, is an advanced quantum chemistry method that extends Configuration Interaction (CI) by incorporating single, double, and triple excitations in its calculations. This approach provides a more comprehensive representation of electronic correlations in molecular systems, resulting in improved accuracy for predicting molecular properties and behaviors. CISDT is particularly useful in studying complex molecules where higher-order excitations significantly influence the results.
