For structural studies of biological solids, high resolution distance measurements using solid-state nuclear magnetic resonance (NMR) are indispensable techniques, of which rotational-echo double-resonance (REDOR) is one of the most widely used methods. This feature article introduces the basic concepts...
NMR Spectroscopy differs favorably from other physical methods of investigation (IR and UV spectroscopy) in that in some cases it makes it possible to detect directly the formation of intermediate products of chemical reactions (ions, reaction complexes, solvates, etc.). However, it should be ...
19 F-NMR has been shown to offer a number of advantageous qualities for the study of imide chemistry in solution under various conditions. Included among these benefits is the ability to measure many of the separate chemical species present in solution without isolation of products. This 19 F-...

Oil/water two phase displacement experiment can describe macroscopic flow characteristics,but not the microscopic producing status of reservoirs.NMR technology has been applied to study the characteristics of oil/water two phase flow from microscopic perspective.The displacement performance of oil displacing...
Emphasis is placed on the complementary use of SNIF-NMR (site-specific natural isotopic fractionation nuclear magnetic resonance) and IRMS (isotope-ratio mass spectrometry) in association with chemometric methods for detecting the adulteration.关键词: Nuclear magnetic resonance Mass spectrometry Stable ...
High-resolution nuclear magnetic resonance (NMR) and Fourier transform infrared (FTIR) spectroscopy experiments were applied to obtain detailed information on the hydrocarbon chemistry of three light and three heavy crude oils. Quantitative fractions of aromatic molecules and functional groups constituting oi...
