What Does ZCCSD Stand For?

ZCCSD stands for Z Vector Coupled Cluster With Single And Double Excitation

ZCCSD, or Z Vector Coupled Cluster With Single And Double Excitation, is a high-level quantum chemistry method that employs a coupled cluster framework to accurately describe the electronic structure of many-body quantum systems. By incorporating both single and double excitations, ZCCSD effectively captures dynamic electron correlation effects, making it a powerful tool for investigating molecular properties and reactions. This method is particularly useful in applications requiring high precision, such as in computational studies of complex molecular environments and interactions.
