What Does CISDQ Stand For?

CISDQ stands for Configuration Interaction With Single Double And Quadruple Excitations

CISDQ, or Configuration Interaction with Single, Double, and Quadruple Excitations, is a sophisticated quantum chemistry method used to describe electronic states of molecular systems. This approach extends traditional configuration interaction techniques by incorporating excitations involving single, double, and quadruple electron transitions. By accounting for a broader range of electron correlations, CISDQ provides enhanced accuracy in predicting molecular properties and behavior, making it a valuable tool for researchers in computational chemistry and related fields.
