The chemical shift of the proton at position 2 in the imidazolium ring of 1-decyl-3-methyl-imidazolium (H2) is rather different for all three samples, reflecting the shifting equilibrium between the contact pairs and free fully solvated ions. Classical molecular dynamics simulations of the 1-decyl-3-methyl-imidazolium chloride contact ion pair as well as of free ions in water, acetonitrile, and dichloromethane have been conducted, and the quantum mechanics\/molecular mechanics methods have been applied to predict NMR chemical shifts for the H2 proton. The chemical shift of the H2 proton was found to be primarily modulated by hydrogen bonding with the chloride anion, while the influence of the solvents\u2500though differing in polarity and capabilities for hydrogen bonding\u2500is less important. By comparing experimental and computational results, we deduce that complete disruption of the ionic liquid into free ions takes place in an aqueous solution. Around 23% of contact ion pairs were found to persist in acetonitrile. Ion-pair breaking into free ions was predicted not to occur in dichloromethane.<\/jats:p>","DOI":"10.1021\/acs.jpcb.0c07450","type":"journal-article","created":{"date-parts":[[2020,11,12]],"date-time":"2020-11-12T22:40:53Z","timestamp":1605220853000},"page":"10776-10786","source":"Crossref","is-referenced-by-count":14,"title":["Computational NMR Study of Ion Pairing of 1-Decyl-3-methyl-imidazolium\nChloride in Molecular Solvents"],"prefix":"10.1021","volume":"124","author":[{"given":"Dovile\u0307","family":"Lengvinaite\u0307","sequence":"first","affiliation":[{"name":"Vilnius University , , Saule\u0307tekio al. 3 , ,","place":["Vilnius, Lithuania, LT-10257"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vytautas","family":"Klimavic\u030cius","sequence":"additional","affiliation":[{"name":"Vilnius University , , Saule\u0307tekio al. 3 , ,","place":["Vilnius, Lithuania, LT-10257"]},{"name":"University of Technology Darmstadt , , ,","place":["Darmstadt, Germany, D-64287"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3770-1471","authenticated-orcid":true,"given":"Vytautas","family":"Balevicius","sequence":"additional","affiliation":[{"name":"Vilnius University , , Saule\u0307tekio al. 3 , ,","place":["Vilnius, Lithuania, LT-10257"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1359-3573","authenticated-orcid":true,"given":"Ke\u0328stutis","family":"Aidas","sequence":"additional","affiliation":[{"name":"Vilnius University , , Saule\u0307tekio al. 3 , ,","place":["Vilnius, Lithuania, LT-10257"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2020,11,12]]},"reference":[{"key":"2026090314265509000_cit1","doi-asserted-by":"publisher","first-page":"2071","DOI":"10.1021\/cr980032t","article-title":"Room-Temperature\nIonic Liquids.
