Phys. accepted article (2020), DOI: 10.1039/D0CP00334D Changes since v2.0: added reference_lengths.xlsx file listing the current bond lengths for benchmarking added Ne - OCS rm(2) structure and deprecated Ne - OCS reSE bond lengths. Changes since v1.0: added DMS - SO2 and Xe - OCS added NCDT.py to facilitate interaction energy benchmarking in Psi4

Unless noted otherwise, all interaction energies calculated on LUIS at Leibniz University Hannover, with funding from Lower Saxony Ministry of Science and Culture (NI MWK) and the German Research Association (DFG). DMS - SO2 and Xe-OCS interaction energies calculated on Zeus at Pawsey Supercomputing Centre, with funding from the Australian Government and the Government of Western Australia.
