title: Probing ionic liquid aqueous solutions using temperature of maximum density isotope effects.
abstract: This work is a new development of an extensive research program that is investigating for the first time shifts in the temperature of maximum density (TMD) of aqueous solutions caused by ionic liquid solutes. In the present case we have compared the shifts caused by three ionic liquid solutes with a common cation-1-ethyl-3-methylimidazolium coupled with acetate, ethylsulfate and tetracyanoborate anions-in normal and deuterated water solutions. The observed differences are discussed in terms of the nature of the corresponding anion-water interactions.
