¹⁵N NMR studies provide insights into physico-chemical properties of room-temperature ionic liquids.

ABSTRACT: Ionic liquids (ILs) have gained a lot of attention as alternative solvents in many fields of science in the last two decades. It is known that the type of anion has a significant influence on the macroscopic properties of the IL. To gain insights into the molecular mechanisms responsible for these effects it is important to characterize these systems at the microscopic level. Such information can be obtained from nuclear spin-relaxation studies which for compounds with natural isotope abundance are typically performed using direct 1H or 13C measurements. Here we used direct 15N measurements to characterize spin relaxation of non-protonated nitrogens in imidazolium-based ILs which are liquid at ambient temperature. We report heteronuclear 1H-15N scalar coupling constants (nJHN) and 15N rela
