What Does CCSDTQP Stand For?

CCSDTQP stands for CCSDTQ And Pentuple Excitations

CCSDTQP stands for "CCSDTQ And Pentuple Excitations." It refers to a sophisticated computational method in quantum chemistry that combines Coupled Cluster Theory with Single, Double, Triple, Quadruple, and Pentuple excitations. This approach is designed to accurately describe electronic correlations in many-body systems, making it particularly valuable for studying complex molecular interactions and properties. The method enhances predictive accuracy for chemical phenomena by accounting for higher-order excitations beyond traditional coupled cluster models.
