Authors: Yanes-Rodriguez, Raquel; Prosmiti, Rita Journal: PHYSICAL CHEMISTRY CHEMICAL PHYSICS Publication date: 2022/01/19 DOI: 10.1039/d1cp04935f Abstract: We have assessed the performance and accuracy of different wavefunction-based electronic structure methods, such as DFMP2 and domain-based local pair-natural orbital (DLPNO-CCSD(T)), as well as a variety of density functional theory (DFT) approaches on He@(H2O)(N) cage systems. We have [...]

Authors: Braunstein, Matthew; Bonnet, Laurent; Roncero, Octavio Journal: PHYSICAL CHEMISTRY CHEMICAL PHYSICS Publication date: 2022/03/02 DOI: 10.1039/d1cp04244k Abstract: We present quasi-classical trajectory (QCT) cross sections, rate constants, and product state distributions for the D + H-3(+) -> H2D+ + H reaction. Using the same H-4(+) potential surface, the rate constants obtained from several QCT-based methods [...]
