Various spectroscopic methods are employed to investigate the slowing down of hydration bond dynamics in the proximity of both anions and cations. To date, most of these studies have primarily focused on the properties of binary systems. However, in comparison to ion\u2013water binary systems, ternary systems that involve ions, water, and organic matter are more prevalent in nature and provide more realistic insights into biological processes. This study focuses on ion hydration in water and alcohol mixture using terahertz spectroscopy and x-ray diffraction (XRD). The results reveal a distinct behavior depending on the type of alcohol used. Specifically, the presence of both methanol and ethanol results in the disappearance of absorption peaks associated with NaCl hydrate at low temperatures. In contrast, tert-butanol does not exhibit such an effect, and isopropanol demonstrates a more complex response. By combining these terahertz spectroscopic findings with low-temperature XRD data, we gain insights into the formation, or lack thereof, of NaCl\u2009\u00b7\u20092H2O hydrate crystals. Crucially, our observations suggest a dominant correlation between the polarity of the alcohol molecules and its impact on the Na+ hydration. Strongly polar alcohols preferentially solvating the Na+ ion lead to the failure of hydrate formation, while weakly polar alcohols do not have this effect.<\/jats:p>","DOI":"10.1063\/5.0205781","type":"journal-article","created":{"date-parts":[[2024,5,16]],"date-time":"2024-05-16T06:04:47Z","timestamp":1715839487000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":4,"title":["Terahertz fingerprint reveals the effect of alcohols on sodium ions hydration shell"],"prefix":"10.1063","volume":"160","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1296-1979","authenticated-orcid":false,"given":"Yuyue","family":"Yan","sequence":"first","affiliation":[{"name":"Centre for Terahertz Waves and College of Precision Instrument and Optoeletronics Engineering, Tianjin University 1 , Tianjin 300072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ligang","family":"Chen","sequence":"additional","affiliation":[{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences 2 , Chongqing 400714, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaqi","family":"Zhang","sequence":"additional","affiliation":[{"name":"Centre for Terahertz Waves and College of Precision Instrument and Optoeletronics Engineering, Tianjin University 1 , Tianjin 300072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7073-0661","authenticated-orcid":false,"given":"Guanhua","family":"Ren","sequence":"additional","affiliation":[{"name":"Hebei Key Laboratory of Physics and Energy Technology, Department of Mathematics and Physics, North China Electric Power University 3 , Baoding 071003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Zhou","sequence":"additional","affiliation":[{"name":"Medical Science and Technology Innovation Center, Shandong First Medical University and Shandong Academy of Medical Sciences 4 , Jinan 250021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7050-3792","authenticated-orcid":false,"given":"Liyuan","family":"Liu","sequence":"additional","affiliation":[{"name":"Centre for Terahertz Waves and College of Precision Instrument and Optoeletronics Engineering, Tianjin University 1 , Tianjin 300072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7712-3365","authenticated-orcid":false,"given":"Xueqian","family":"Zhang","sequence":"additional","affiliation":[{"name":"Centre for Terahertz Waves and College of Precision Instrument and Optoeletronics Engineering, Tianjin University 1 , Tianjin 300072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9413-9630","authenticated-orcid":false,"given":"Chunmei","family":"Ouyang","sequence":"additional","affiliation":[{"name":"Centre for Terahertz Waves and College of Precision Instrument and Optoeletronics Engineering, Tianjin University 1 , Tianjin 300072, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5342-0672","authenticated-orcid":false,"given":"Huabin","family":"Wang","sequence":"additional","affiliation":[{"name":"Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences 2 , Chongqing 400714, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9425-9635","authenticated-orcid":false,"given":"Jiaguang","family":"Han","sequence":"additional","affiliation":[{"name":"Centre for Terahertz Waves and College of Precision Instrument and Optoeletronics Engineering, Tianjin University 1 , Tianjin 300072, China"},{"name":"Guangxi Key Laboratory of Optoelectronic Information Processing, School of Optoelectronic Engineering, Guilin University of Electronic Technology 5 , Guilin 541004, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2024,5,16]]},"reference":[{"key":"2024051610040471000_c1","doi-asserted-by":"publisher","first-page":"15","DOI":"10.1016\/j.molliq.2003.08.013","article-title":"X-ray diffraction investigations of concentrated aqueous solutions of calcium halides","volume":"110","year":"2004","journal-title":"J.\u00a0Mol.
