The experimental results served to assess the accuracy of a low-cost yet accurate computational strategy, which relies on a simplified characterization of the HCN-N2 interaction potential, and employs a novel approximate method of solving the quantum scattering problem. Building on the validation of this computational approach, the dataset was extended to higher rotational transitions, up to J(HCN)=5","authors_text":"Cristina Puzzarini, Fran\\c{c}ois Lique, Francesca Tonolo, Hubert J\\'o\\'zwiak, Luca Bizzocchi, Mattia Melosso, Piotr Wcis{\\l}o","cross_cats":["astro-ph.EP"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.chem-ph","submitted_at":"2025-05-19T09:22:22Z","title":"Experimental and theoretical investigation on N2 pressure-induced coefficients of the lowest rotational transitions of HCN"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2505.13560","kind":"arxiv","version":2},"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":"sha256:2b9ac43cf0bb779357633a62274ce78ca851e56f8c6a57150fde8f649e3033e0","target":"record","created_at":"2026-07-05T11:06:32Z","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":"b6a5f8273af7094cc70b337e0f1b1a8e8c361aae022ef6bb5b1476d21cc1fd07","cross_cats_sorted":["astro-ph.EP"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.chem-ph","submitted_at":"2025-05-19T09:22:22Z","title_canon_sha256":"b6ecb074e32ba98fe8989df92f04b4fbef616ba6da6242672ab3ae67e4b61e1e"},"schema_version":"1.0","source":{"id":"2505.13560","kind":"arxiv","version":2}},"canonical_sha256":"8cd0521c220bae9f34f046020e176ecf7b7541a0d2221ac446a631686f676322","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8cd0521c220bae9f34f046020e176ecf7b7541a0d2221ac446a631686f676322","first_computed_at":"2026-07-05T11:06:32.942187Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:06:32.942187Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UctTK4W8GMrN/wMGbtw37oX5CArNnUKwR4GbdyCLjGW3xAlEip/zwLB8z/wtu7x9UHLxwLQO75IxnMsZuBVxDA==","signature_status":"signed_v1","signed_at":"2026-07-05T11:06:32.942645Z","signed_message":"canonical_sha256_bytes"},"source_id":"2505.13560","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2b9ac43cf0bb779357633a62274ce78ca851e56f8c6a57150fde8f649e3033e0","sha256:90d1c460967181fdb37221e330bb5e116c78062858c7bf1237b9185eda95fa98"],"state_sha256":"86a76b4eac0f8b9430d2fb08741fe68db3c8fcbd20d76f495c1605d852049015"}
