Abstract As new green solvents and functional materials ,room temperature ionic liquids ( ILs) have attracted great
attention. The present paper reviews the applications of NMR techniques in the research of structure ,properties , and
interactions of cations with anions of ILs ,interactions between ILs and the pounds ,the dynamic characteristics of
ILs and their mixtures ,the aggregation behavior of ILs in solutions ,and the determination of thermodynamic parameters of
ILs.
