Application of Computational Chemical Shift Prediction Techniques to the Cereoanhydride Structure Problem-Carboxylate Complications. [PDF]
, 2017 Despite the vast array of techniques available to modern-day chemists, structural misassignments still occur. These misassignments are often only realized upon attempted synthesis, when the spectra of synthesized products do not match previously reported

Synthesis of Substituted Phenyl N-(2-hydroxybenzyl)-N-Methylcarbamates
Molecules, 2002 Thirteen previously unreported substituted phenyl N-(2-hydroxybenzyl)-Nmethylcarbamates were prepared by the reaction of substituted 2-hydroxybenzyl-Nmethylamines with phenyl chlorocarbonates. They were identified by their 1H- and 13C-NMR spectra.

www.nmrdb.org: Resurrecting and Processing NMR Spectra On-line
CHIMIA, 2008 NMR spectroscopy is certainly the analytical methodology that provides the most information about a molecule but the long-term vision of this information is often lacking. We present here two innovative tools accessible free from the web.

Spin-modulated quasi-1D antiferromagnet LiCuVO_4
, 2007 We report on magnetic resonance studies within the magnetically ordered phase of the quasi-1D antiferromagnet LiCuVO_4. Our studies reveal a spin reorientational transition at a magnetic field H_c1 ~ 25 kOe applied within the crystallographical (ab ...
