Why Nondynamic Correlation Matters for ππ Stacking? Lessons from the Benzene Dimer Link here: https://doi.org/10.1021/acs.jpclett.5c02576 Abstract: Two leading methods for benchmarking ππ interactions are fixed-node diffusion Monte Carlo (DMC) and coupled cluster with singles, doubles, and perturbative triples [CCSD(T)]. The parallel-displaced benzene dimer (BZPD) is a key model for assessing the performance of theoretical approaches in describing…
