Our findings are in contradiction with a previous proposal. We present a simple application of the newly derived formula to the case of a triplet ground state split by an easy-plane ZFS spin Hamiltonian. When $kT$ is much smaller than the ZFS gap, thus a single non-degenerate level is thermally populated, our approach correctly predicts a temperature-independent paramagnetic shift, while the previous theory leads to a Curie tempe","authors_text":"Alessandro Soncini, Willem Van den Heuvel","cross_cats":["physics.atm-clus"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2012-12-16T20:52:22Z","title":"Paramagnetic NMR chemical shift in a spin state subject to zero-field splitting"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1212.3830","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":"sha256:8a7c79b15d88b00130f5555bfac4d8f7129dbb559b98dcf226123cb0f7c9167e","target":"record","created_at":"2026-05-18T02:56:44Z","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":"28628b3169552e875c96865b7e4be458b88d83816e8b5950657d2b095026a2b7","cross_cats_sorted":["physics.atm-clus"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2012-12-16T20:52:22Z","title_canon_sha256":"d32fdcbdd8b4ffdc252957c2a0fed6e89c3c8773dbbde2e3719d53c40fe419ca"},"schema_version":"1.0","source":{"id":"1212.3830","kind":"arxiv","version":1}},"canonical_sha256":"a2a49115f562f4a6998cca93146e9336850a48d4c957b47111b7b4bbec6b49e5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a2a49115f562f4a6998cca93146e9336850a48d4c957b47111b7b4bbec6b49e5","first_computed_at":"2026-05-18T02:56:44.405267Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:56:44.405267Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1x+Bw6bmIy6VrLHO4Q61EtH3E93raTEoADc6cgMM1NxoCjh2OmcnmvkCaHUkbLRhfPbVAoiExf8+YSDojbHADQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:56:44.405755Z","signed_message":"canonical_sha256_bytes"},"source_id":"1212.3830","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8a7c79b15d88b00130f5555bfac4d8f7129dbb559b98dcf226123cb0f7c9167e","sha256:3b628e71b7da2f0e5405395408aa86a1e0f1d431a02cf11e1df9bfd10d896d9d"],"state_sha256":"6797fab005190bf07c1c689fa2f7399c6f8d599b9793dd090a7d2ccbffea9f82"}
