Applications of nuclear magnetic resonance to determine the structure and interactions of ligands, peptides and enzymes
(1996)
Nuclear magnetic resonance (NMR) spectroscopy is emerging as a powerful tool for the study of enzyme structure and function. This article discusses the general principles of NMR and the potential information this technique ...
Magnetic resonance study of the crystallization behavior of InF3-based glasses doped with Cu2+, Mn2+ and Gd3+
(2006-09-15)
The crystallization of fluoroindate glasses doped with Gd3+, Mn2+ and Cu2+ heat treated at different temperatures, ranging from the glass transition temperature (Tg) to the crystallization temperature (Tc), are investigated ...
NMR-SSC magnetic field profiler applied to magnetic field shimming
(Institute of Electrical and Electronics Engineers, 2013-02)
A new methodology aimed to control the spatial dependence of a magnetic field within a volume of interest is described. The designed hardware uses Nuclear Magnetic Resonance (NMR) to sense the magnetic field. A modified ...

Experimental NMR and MS study of benzoylguanidines. Investigation of E/Z isomerism
(2013-04-01)
Molecules containing the guanidinic nuclei possess several pharmacological applications, and knowing the preferred isomers of a potential drug is important to understand the way it operates pharmacologically. Benzoylguanidines ...
Communiols E-H: New polyketide metabolites from the coprophilous fungus Podospora communis
(2005-03-01)
Communiols E-H (1-4), four new polyketide-derived natural products containing furanocyclopentane, furanocyclopentene, cyclopentene, or γ-lactone moieties, have been isolated from two geographically distinct isolates of the ...
