Hydrogen Bonding in Concentrated Aqueous Solutions of 1,2-Dimethoxyethane: Formation of Water Clusters

摘要: The hydrogen bonding in concentrated aqueous solutions of 1,2-dimethoxyethane was studied by Raman spectroscopy the O−H stretching band water at various concentrations temperature range 218−315 K. isotropic spectra were analyzed decomposition, and two major components identified spectra. They assigned to vibrations monomers molecules participating clusters, respectively. following picture hydration structure emerged. Water can exist stable configurationseither clusters enclosed cavities molecules, or as bridging ether oxygen atoms. clustering is driven cooperative strengthening bonds clusters. are mutually stabilized extensive bonding, size almost...
