Consequently, the binding energy of the hemibonded structure (H2O)2+ is not well-defined. For a comprehensive comparison of different functionals for this system, we propose three criteria: (i) The binding energies, (ii) the relative energies between the conformers of the water dimer radical cation, and (iii) the dissociation curves pred","authors_text":"Jeng-Da Chai, Jer-lai Kuo, Ming-Kang Tsai, Piin-Ruey Pan, You-Sheng Lin","cross_cats":["cond-mat.soft","physics.atm-clus","physics.comp-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2012-04-06T17:33:02Z","title":"Assessment of density functional approximations for the hemibonded structure of water dimer radical cation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1204.1522","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:cefdcc1f3bd15fa1a052d724a68dac2d0bdad456ff17e67fad6da68f47b0b8eb","target":"record","created_at":"2026-05-18T00:37:02Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"93867b138f705c52b4d153b5d2deaa097fe98d04ce7a828c85c525e5d11a3d0b","cross_cats_sorted":["cond-mat.soft","physics.atm-clus","physics.comp-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2012-04-06T17:33:02Z","title_canon_sha256":"407c542e0f6cc0b870ef91d915db3c4e118734ebb6e8c8af1d89b7537b60ca83"},"schema_version":"1.0","source":{"id":"1204.1522","kind":"arxiv","version":1}},"canonical_sha256":"d42981528904acb6042dcac7b5643929efc3831403556913d669aabba9748ca6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d42981528904acb6042dcac7b5643929efc3831403556913d669aabba9748ca6","first_computed_at":"2026-05-18T00:37:02.833591Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:37:02.833591Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Shn4N0PpMP76n2C5UCPaoXE+zb8YJoKla7Rg4VEQJszZ87uTHgDzhKDqYYTkH+FwKi+ZrdKn7DLZFinV5VifAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:37:02.834041Z","signed_message":"canonical_sha256_bytes"},"source_id":"1204.1522","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:cefdcc1f3bd15fa1a052d724a68dac2d0bdad456ff17e67fad6da68f47b0b8eb","sha256:32619b2299c09f6830e8bc2a798055b8e81125dc0b06caa388004bf6f5b948df"],"state_sha256":"d3b5213b25e24d399c7c55bc7c59342543eb91fe25886c2d533c613efcb8af1c"}
