-NMR spectra of solids
The equations of motion of dipolar-coupled spins of I = 1/2 placed on a rigid lattice are solved approximately in the high-temperature and high-field limit. The NMR-spectra predicted by this theory are in close agreement with both the theoretical spectral moments, up to the eighth in the case of a simple cubic lattice, and the extremely accurate experimental results which have been obtained in ...
متن کاملH–C NMR spectra
Background: Interest in the detailed lignin and polysaccharide composition of plant cell walls has surged within the past decade partly as a result of biotechnology research aimed at converting biomass to biofuels. High-resolution, solution-state 2D H–C HSQC NMR spectroscopy has proven to be an effective tool for rapid and reproducible fingerprinting of the numerous polysaccharides and lignin c...
متن کاملSpectra Part 2 - 1 - Analysis of NMR Spectra
NMR analysis is a complex topic, from both the spectral interpretation and fundamental physics points of view. This section supplements the text on both of these fronts by first providing a concise summary of important general material, followed by the background necessary to interpret H-NMR spectra for molecules that have more complex signal splitting patterns. We assume that you are already f...
متن کاملAB Initio Calculations of NMR Spectra for H20114C9N4 As A New Nanosemiconductor Molecule
BCN compounds have been researched theoretically and experimentally widely. In this paper, weintroduce the theoretical prediction of ternary B-C-N compounds. NMR spectroscopy was employedextensively to study these ternary nanostructures. We discuss the utilization of chemical shiftinformation as well as ab initio calculations of nuclear shielding for H20134C9N4 structuredetermination. We calcul...
متن کاملInfrared and NMR Spectra of Arylsulphonamides , 4
Several arylsulphonamides of the configuration, 4-X-C6H4SO2NH2 (where X1⁄4H; CH3; C2H5; F; Cl; Br; I or NO2) and i-X, j-YC6H3SO2NH2 (where i-X, j-Y1⁄4 2,3-(CH3)2; 2,4-(CH3)2; 2,5-(CH3)2; 2-CH3,4-Cl; 2-CH3,5-Cl; 3-CH3,4-Cl; 2,4-Cl2 or 3,4-Cl2) were prepared, and their infrared spectra were measured in the solid state. The NMR spectra were recorded in solution. N H asymmetric and symmetric stretc...
