However, in the presence of methane or other help gases, clathrate hydrates of these substances have been synthesized. In this work, molecular dynamics simulations are used to characterize guest-host hydrogen bonding, microscopic structures, and guest dynamics of binary structure II clathrate hydrates of methane (small cages) with ethanol, 1-propanol, and 2-propanol in the temperature range of 100\u2013250 K to gain insight into the stability of these materials. We observe that these alcohols form structures with dynamic long-lived (\u223c10 ps) guest-host hydrogen bonds in the hydrate phases while maintaining the general cage structure of the sII clathrate hydrate form. The hydroxyl groups of ethanol, 1-propanol, and 2-propanol act as both proton acceptors and proton donors and there is a considerable probability of simultaneous hydrogen bonding between O and H hydroxyl atoms with different cage water molecules. The presence of the nonpolar methane molecule and the hydrophobic moieties of the alcohols stabilize the hydrate phase, despite the strong and prevalent alcohol-water hydrogen bonding. The effect of the alcohol molecules on the structural properties of the hydrate and the effect of guest-host hydrogen bonding on the guest dynamics are studied.<\/jats:p>","DOI":"10.1063\/1.3469776","type":"journal-article","created":{"date-parts":[[2010,8,19]],"date-time":"2010-08-19T23:05:04Z","timestamp":1282259104000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":126,"title":["Hydrogen-bonding alcohol-water interactions in binary ethanol, 1-propanol, and 2-propanol+methane structure II clathrate hydrates"],"prefix":"10.1063","volume":"133","author":[{"given":"Saman","family":"Alavi","sequence":"first","affiliation":[{"name":"University of Ottawa 1 Department of Chemistry, Centre for Catalysis Research and Innovation, , Ottawa, Ontario K1N 6N5, Canada"},{"name":"Keio University 2 Department of Mechanical Engineering, , Yokohama, Kanagawa 223-8522, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Takeya","sequence":"additional","affiliation":[{"name":"National Institute of Advanced Industrial Science and Technology (AIST) 3 Research Institute of Instrumentation Frontier, , Tsukuba, Ibaraki 305-8565, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryo","family":"Ohmura","sequence":"additional","affiliation":[{"name":"Keio University 2 Department of Mechanical Engineering, , Yokohama, Kanagawa 223-8522, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom K.","family":"Woo","sequence":"additional","affiliation":[{"name":"University of Ottawa 1 Department of Chemistry, Centre for Catalysis Research and Innovation, , Ottawa, Ontario K1N 6N5, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John A.","family":"Ripmeester","sequence":"additional","affiliation":[{"name":"National Research Council of Canada 4 Steacie Institute for Molecular Sciences, , Ottawa, Ontario K1A 0R6, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2010,8,18]]},"reference":[{"key":"2023062605085368400_c1","first-page":"115","volume-title":"Water, A Comprehensive Treatise","author":"Franks","year":"1972"},{"key":"2023062605085368400_c2","first-page":"135","volume-title":"Inclusion Compounds","author":"Atwood","year":"1984"},{"key":"2023062605085368400_c3","volume-title":"Clathrate Hydrates of Natural Gases","year":"2007","edition":"3rd ed."},{"key":"2023062605085368400_c4","doi-asserted-by":"publisher","first-page":"9106","DOI":"10.1021\/jp8006848","volume":"112","year":"2008","journal-title":"J.
