Characterization of doubly ionic hydrogen bonds in protic ionic liquids by NMR deuteron quadrupole coupling constants - Differences to H-bonds in amides, peptides and proteins
We present the first deuteron quadrupole coupling constants (DQCC) for selected protic ionic liquids (PILs) measured by solid-state NMR spectroscopy. The experimental data are supported by dispersion-corrected density functional theory (DFT-D3) calculations and molecular dynamics (MD) simulations. The DQCCs of the N-D bond in the triethylammonium cations are the lowest reported for deuterons in PILs indicating...

Journal Highlight: Molecular dynamics and composition of crude oil by low-field nuclear magnetic resonance
http://www.spectroscopynow.com/common/images/thumbnails/156c1d97dbe.jpgLow-field NMR relaxation measurements have been used to reveal the composition of crude oil, offering a low-cost method that can be used under poor working conditions in the field and in the wellbore.

Ionic liquids: Enzymatic cellulose processing
Ionic liquids: Enzymatic cellulose processing
http://www.spectroscopynow.com/common/images/thumbnails/1514834b12b.jpgThe promise of room temperature ionic liquids (RTILs) as alternatives to toxic and inflammable volatile organic solvents for green chemistry has been on the boil for at least a couple of decades. Now, team has found that enzymatic activity can be sustained in processing cellulose, from wood, for conversion of this raw material into other useful compounds.

Electron Spin–Lattice Relaxation Mechanisms of Nitroxyl Radicals in Ionic Liquids and Conventional Organic Liquids: Temperature Dependence of a Thermally Activated Process
From The DNP-NMR Blog:
Electron Spin–Lattice Relaxation Mechanisms of Nitroxyl Radicals in Ionic Liquids and Conventional Organic Liquids: Temperature Dependence of a Thermally Activated Process
A detailed understanding of the electron-spin relaxation mechanisms in polarizing agents used for DMP-NMR spectroscopy is crucial for the understanding of the DNP process and to optimize polarizing agents for different DNP applications. The entire study was performed at X-Band frequencies (9 GHz, 14 MHz 1H) and provides many details about the relaxation behavior of nitroxide radicals -...

Post-Doc fellowship in NMR Methods to Study Ionic Solids/liquids - Univ. of Aveiro/Lisbon (Portugal)
A 1-year postdoctoral position is available starting from January 2011, (extendable for additional 12 months) to study the “solid structure” of ionic liquids (ILs) and ionic solids (ISs) with relevance to the pharmaceutical industry. The research will be centred in the use of NMR techniques in tandem with molecular modelling to study the physical chemistry of molecular interactions in ILs and ISs. The project will be performed at the NMR centres at the Universities of Aveiro (solid state...
