NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities.
Journal of Organic Chemistry, 1997In the course of the routine use of NMR as an aid for organic chemistry, a day-to-day problem is the identification of signals deriving from common contaminants (water, solvents, stabilizers, oils) in less-than-analytically-pure samples. This data may be

Flavoproteins are involved in a wide variety of enzymatic reactions like oxidation, reduction and mono-oxygenation. Consequently, flavin cofactors occur in many different forms including, for example, the oxidized semiquinone and reduced states as well as the C4a-(hydro)peroxyflavin form.

Investigation of exchange processes by two‐dimensional NMR spectroscopy
, 1979A new general technique for the investigation of exchange processes in molecular systems is proposed and demonstrated. Applications comprise the study of chemical exchange, of magnetization transfer by inter‐ and intramolecular relaxation in liquids, and

IEEE Journal of Solid-State Circuits, 2011
In our earlier work, we developed a 2-kg NMR system, which was 60 X lighter, 40× smaller, yet 60× more spin-mass sensitive than a 120-kg state-of-the-art commercial benchtop system. Here we report on two new nuclear magnetic resonance (NMR) systems that represent further orders-of-magnitude size reduction and lab-on-a-chip capability. The first system,

Nuclear magnetic resonance, or NMR, is the energy exchange between an RF magnetic field and an atomic nucleus such as a hydrogen proton, which is a tiny bar magnet due to its spin. NMR has a broad array of powerful applications, including: biomolecule sensing (e.g., cancer marker detection), medical imaging, and oil detection. NMR instruments, however,

1H-NMR and 77Se-NMR in CsHSeO4
Solid State Ionics, 2005Abstract Measurements of 1 H-NMR and 77 Se-NMR have been conducted with CsHSeO 4 , in order to clarify dynamics of proton and SeO 4 tetrahedron which is related to transport of proton below and above T c = 401 K. An NMR absorption line is observed in 1 H-NMR measurement and its line width decreases with increasing temperature below T c , due

Nuclear magnetic resonance (NMR) offers a powerful new probe of the body's internal anatomy and function. The technique utilizes a combination of static and radio frequency (RF) magnetic fields to excite a weak resonant magnetic field emission from various selected naturally abundant nuclei in the body such as hydrogen (1H), phosphorus (31P) and carbon
