The dynamics of negative ions have been investigated by recording time\u2010of\u2010flight mass spectra in a wide range of collision energies from 17.5 to 350\u2005eV in the lab frame, where the branching ratios show a relevant energy dependence for low\/intermediate collision energies. The dominant fragmentation channel in the whole energy range investigated has been assigned to the hydroxyl anion in contrast to oxygen anion from dissociative electron attachment (DEA) experiments. This result shows the relevant role of the electron donor in the vicinity of the temporary negative ion formed allowing access to reactions which are not thermodynamically attained in DEA experiments. The electronic state spectroscopy of such negative ions, was obtained from potassium cation energy loss spectra in the forward scattering direction at 205\u2005eV impact energy, showing a prevalent Feshbach resonance at 9.36\u00b10.10\u2005eV with \n character, while a less pronounced \n contribution assigned to a shape resonance has been obtained at 3.16\u00b10.10\u2005eV. Quantum chemical calculations for the lowest\u2010lying unoccupied molecular orbitals in the presence of a potassium atom have been performed to support the experimental findings.<\/jats:p>","DOI":"10.1002\/cphc.202400314","type":"journal-article","created":{"date-parts":[[2024,4,17]],"date-time":"2024-04-17T10:14:10Z","timestamp":1713348850000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Low\u2010lying Negative Ion States Probed in Potassium \u2013 Ethanol Collisions"],"prefix":"10.1002","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4613-0372","authenticated-orcid":false,"given":"Ana Isabel","family":"Lozano","sequence":"first","affiliation":[{"name":"Atomic and Molecular Collisions Laboratory CEFITEC Department of Physics Universidade NOVA de Lisboa  2829-516 Caparica Portugal"},{"name":"Institut de Recherche en Astrophysique et Plan\u00e9tologie (IRAP) Universit\u00e9 Toulouse III - Paul Sabatier CNRS CNES  9 Avenue du Colonel Roche 31028 Toulouse France"},{"name":"Chemical Sciences Division Lawrence Berkeley National Laboratory  One Cyclotron Road Berkeley 94720 California USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1996-9925","authenticated-orcid":false,"given":"Sarvesh","family":"Kumar","sequence":"additional","affiliation":[{"name":"Atomic and Molecular Collisions Laboratory CEFITEC Department of Physics Universidade NOVA de Lisboa  2829-516 Caparica Portugal"},{"name":"Institut de Recherche en Astrophysique et Plan\u00e9tologie (IRAP) Universit\u00e9 Toulouse III - Paul Sabatier CNRS CNES  9 Avenue du Colonel Roche 31028 Toulouse France"},{"name":"Chemical Sciences Division Lawrence Berkeley National Laboratory  One Cyclotron Road Berkeley 94720 California USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4503-3175","authenticated-orcid":false,"given":"Pedro J.
