title: Non-covalent Dimers and Trimers (NCDT) database

description: <strong>Non-Covalent Dimers and Trimers (NCDT) database</strong> Database of equilibrium geometries of benchmark-quality, as well as accurate interaction energies at the specified geometries. NCDT.py is a Psi4 database module, executable with: <pre><code class="language-python">db(method, "NCDT")</code></pre> Optional arguments are subsets of the database: subset = "16": original NCDT16 from [1] subset = "17": first revised version including Xe-OCS, DMS-SO2, and excluding Ne-OCS subset = "HB": hydrogen-bonded complexes only subset = "DD": dispersion-dominated complexes only subset = "MX": mixed interaction complexes only Contents: Ne - C<sub>2</sub>H<sub>4</sub> semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z Ar - C<sub>2</sub>H<sub>4</sub> semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z Ne - OCS semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z Ar - OCS semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z Kr - OCS semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z HCl - H<sub>2</sub>CO semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z HF - H<sub>2</sub>CO semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z HCN - H<sub>2</sub>CO semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z CS<sub>2</sub> - OCS semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z CH<sub>2</sub>ClF - HCCH semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z HCCH - HCCH semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z Ne - Ne - NNO semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z Ne - Ar - NNO semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z Ar - Ar - NNO semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z Ne - Ar - HCl semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z HF - HF - NH<sub>3</sub> semi-experimental structure, based on B2PLYP-D3BJ anharmonic corrections [1] interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z DMS - SO<sub>2</sub> semi-experimental structure, based on ChS corrections [2], xyz reconstructed from SI data interaction energy from counterpoise-corrected recipe: HF/cc-pv[tq5]z MP2/cc-pv[q5]z CCSD(T)/cc-pv[tq]z Xe - OCS experimental mass-dependent structure [3], note: O=C distance unreliable interaction energy from counterpoise-corrected recipe: HF/cc-pwcv[tq5]z-pp MP2/cc-pwcv[q5]z-pp CCSD(T)/cc-pwcv[tq]z-pp References: [1] Kraus, Obenchain and Frank, <em>Benchmark-Quality Semiexperimental Structural Parameters of van der Waals Complexes</em>, J.
