The reaction leading to the formation of the dimethyl ether ion from a methanol molecule interacting with a protonated methanol ion via the elimination of a water molecule is a basic mechanism for the formation of complex organic molecules. Here, we experimentally examine such reactions in the gas phase, analyzing the production and reactivity of protonated cluster ions formed by the ionization of a supersonic jet of methanol. Focusing especially on the post-collisional relaxation of the protonated methanol dimer and trimer ions after high-energy single collisions, the results indicate a strong size selectivity favoring the occurrence of this reaction only in the dimer ion. To elucidate this behavior, the velocity distribution of the eliminated water molecule was measured using an event-by-event coincidence analysis. These results are interpreted using quantum chemical calculations of the dissociation pathways. It turns out that in the dimer case, two transition states are able to contribute to this intracluster reaction. In the trimer case, methanol evaporation appears as the most energetically favorable relaxation pathway.<\/jats:p>","DOI":"10.1063\/5.0190182","type":"journal-article","created":{"date-parts":[[2024,3,4]],"date-time":"2024-03-04T11:27:29Z","timestamp":1709551649000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":5,"title":["Water molecule elimination from the protonated methanol dimer ion\u2014An example of a size-selective intracluster reaction"],"prefix":"10.1063","volume":"160","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-0974-8596","authenticated-orcid":false,"given":"Thibaud","family":"Salbaing","sequence":"first","affiliation":[{"name":"Universit\u00e9 Claude Bernard Lyon 1, IP2I Lyon, UMR 5822, CNRS\/IN2P3 1 , F-69622 Villeurbanne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7075-5941","authenticated-orcid":false,"given":"Denis","family":"Comte","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Claude Bernard Lyon 1, IP2I Lyon, UMR 5822, CNRS\/IN2P3 1 , F-69622 Villeurbanne, France"},{"name":"Institut f\u00fcr Ionenphysik und Angewandte Physik, Leopold Franzens Universit\u00e4t 2 , 6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4572-8612","authenticated-orcid":false,"given":"L\u00e9o","family":"Lavy","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Claude Bernard Lyon 1, IP2I Lyon, UMR 5822, CNRS\/IN2P3 1 , F-69622 Villeurbanne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hector","family":"Lissillour","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Claude Bernard Lyon 1, IP2I Lyon, UMR 5822, CNRS\/IN2P3 1 , F-69622 Villeurbanne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5877-8518","authenticated-orcid":false,"given":"Laura Parrado","family":"Ospina","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Claude Bernard Lyon 1, IP2I Lyon, UMR 5822, CNRS\/IN2P3 1 , F-69622 Villeurbanne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Bertier","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Claude Bernard Lyon 1, IP2I Lyon, UMR 5822, CNRS\/IN2P3 1 , F-69622 Villeurbanne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7472-0639","authenticated-orcid":false,"given":"Linda","family":"Feketeov\u00e1","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Claude Bernard Lyon 1, IP2I Lyon, UMR 5822, CNRS\/IN2P3 1 , F-69622 Villeurbanne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3621-3046","authenticated-orcid":false,"given":"Florent","family":"Calvo","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Grenoble Alpes, CNRS, LIPhy 3 , 38000 Grenoble, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2507-3818","authenticated-orcid":false,"given":"Bernadette","family":"Farizon","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Claude Bernard Lyon 1, IP2I Lyon, UMR 5822, CNRS\/IN2P3 1 , F-69622 Villeurbanne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3446-6146","authenticated-orcid":false,"given":"Michel","family":"Farizon","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Claude Bernard Lyon 1, IP2I Lyon, UMR 5822, CNRS\/IN2P3 1 , F-69622 Villeurbanne, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-5675-1262","authenticated-orcid":false,"given":"Tilmann","family":"M\u00e4rk","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Ionenphysik und Angewandte Physik, Leopold Franzens Universit\u00e4t 2 , 6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2024,3,4]]},"reference":[{"key":"2024030411272376800_c1","doi-asserted-by":"publisher","first-page":"1717","DOI":"10.1021\/jacs.6b00343","volume":"138","year":"2016","journal-title":"J.
