Deuterium quadrupolar tensors of L-histidine hydrochloride monohydrate-[d.sub.7]
Article Abstract:
The deuteron quadrupole coupling constants Cq, asymmetry parameters [eta], and electric field gradient orientation for the imidazolium and primary ammonium groups and for a water of crystallization are determined by a deuterium NMR study at 14 T of a single crystal of L-histidine hydrochloride monohydrate. Density functional cluster calculations give an excellent fit to the imidazolium tensor magnitudes and orientations, when appropriate corrections for vibrational averaging are taken into account.

Hydrogen bonds in ionic liquids revisited: [super 35/37]Cl NMR studies of deuterium isotope effects in 1-n-butyl-3-methylimidazolium chloride
Article Abstract:
The deuterium isotope effects on the chloride ion [super 35/37]Cl NMR signal are used for studying the interionic hydrogen bonds in imidazolium chloride ionic liquids (ILs). This is one of the few examples in which hydrogen-bonding in ILs is examined using deuterium isotope effects and the only one using [super 35/37]Cl NMR to probe these interactions.

Effects of alcohols and counterions on the phase behavior of 1-octyl-3-methylimidazolium chloride aqueous solution
Article Abstract:
The phase behavior of ternary systems involving 1-octyl-3-methylimidazolium chloride, water and different alcohols is examined. The strong interaction between counterions and alcohols has favored the appearance of ordered assemblies.
