Identification of ethanol hydrate complexes by multivariate curve resolution analysis of radial distribution functions

► Component analysis of the O-O RDFs of E-W solutions resolves two complexes of E∙6H2O and 3E∙H2O. ► The water-rich complex E∙6H2O is a disordered relative of the clathrate Istructure. ► E∙6H2O correlates with differences in vodka brands and may be related to alcohol taste perception.
