Magnetic molecular materials resolution

Solid state NMR spectroscopy is used to determine molecular structures by analyzing the static and dynamic features of the material. In NMR experiments, both a magnetic field and a radio frequency field are applied to a solid sample or a solution resulting in an absorption of energy, which is detected as an NMR. Spectrometers are also available for high resolution solid state NMR. Nuclei in...

Abstract The preparation of chiral functional materials with new, improved, and interesting properties is aided tremendously by control of the spatial arrangement of the functional units within them. The use of non-covalent interactions is absolutely critical in this regard, and the molecular-supramolecular balance has to be strictly controlled. The conducting, magnetic and optical properties of chiral materials whose function is profoundly influenced by supramolecular chemistry will be reviewed. Special emphasis is placed on the control of helical arrangements in liquid crystalline systems, in which both chiral induction and spontaneous resolution are important phenomena which can be controlled. 

The ultimate molecular level characterization of a pharmaceutical material is performed on the level of individual chemical environments of each atom in the compound, and this information is best obtained using nuclear magnetic resonance (NMR) spectroscopy. Advances in instrumentation and computer pulse sequences currently allow these studies to be carried out routinely in the solid state.2 Although any nucleus that can be studied in the solution phase also can be studied in the solid state, most work has focused on studies. H-NMR remains an extremely difficult measurement in the solid state, and the data obtained from such work can be obtained only at medium resolution. The main problem is that H-NMR has one of the smallest isotropic chemical shift ranges (12 ppm), but has peak broadening effects that can span several parts per million in magnitude.
