WebDec 19, 1997 · Abstract. The CCSD (T) method was originally motivated as an attempt to treat the effects of triply excited determinants upon both single and double excitation operators on an equal footing. Hence, conventional analyses based on perturbation theory cannot satisfactorily explain why the particular fifth-order term included in CCSD (T) … WebMay 18, 2024 · Using the Gaussian solver with Method 2 is found to be the most effective combination of predicting accurate rate constants when compared against experimental data. ... in all three methods.
