This book describes nuclear magnetic resonance (NMR) methods which are used to study ... such as cement and wood. The results of proton spin-lattice and spin-spin relaxation, cross-relaxation ...

Due to the dangers presented by the NMR magnets and the danger of helium asphyxiation, there are mandatory training requirements (see here for details). Thus, anybody who wants to do work in the NMR ...

The preferred method is based on the investigation of signals in the proton NMR spectrum associated with the lipoproteins. Variations in the size, composition, and density of lipoproteins ...

1 H NMR (42.5 MHz, neat) δ 3.45 (q, J = 7.1, 2 H, H-1), 1.36 (s, 3 H, H-2’), 0.60 (t, J = 7.1, 3 H, H-2). The number of proton environments in this compound are three and it can be observed from the ...

Multivariate analysis of 1 H-NMR spectra of blood sera was reported previously to predict angiographically defined advanced coronary artery disease (CAD) with >90% accuracy and specificity.

To probe the proton configuration and its dynamics at a microscopic level, we performed high-temperature solid-state 1 H magic-angle-spinning nuclear magnetic resonance (NMR) experiments and high ...

As a part of this experiment, students used 1 H-NMR spectroscopy for identifying the key organic ... This, along with an exchangeable proton at 4ppm, indicates that the other compound is most probably ...

The HR-60’s modest success convinced the company that there was a potential market for a low-cost, proton-only NMR spectrometer. Research on such an instrument began in earnest in 1957. It was ...
