Accuracy of Quantum Chemical Methods for Large Noncovalent Complexes [PDF]
Journal of Chemical Theory and Computation, 2013 We evaluate the performance of the most widely used wavefunction, density functional theory, and semiempirical methods for the description of noncovalent interactions in a set of larger, mostly dispersion-stabilized noncovalent complexes (the L7 data set).

Prediction of Rate Constants for Catalytic Reactions with Chemical Accuracy [PDF]
Angewandte Chemie International Edition, 2016 Ex machina: A computational method for predicting rate constants for reactions within microporous zeolite catalysts with chemical accuracy has recently been reported. A key feature of this method is a stepwise QM/MM approach that allows accuracy to be achieved while using realistic models with accessible computer resources.
