Nuclear magnetic resonance practical aspects

Taylor SD, Wright B, Clayton E, Wilson ID, Practical aspects of the use of high performance liquid chromatography combined with simultaneous Nuclear Magnetic Resonance and Mass Spectrometry, Rapid Commun. Mass Spectrom., 12 1732-1736, 1998. [Pg.310]

As an analytical spectroscopic technique, EPR is similar in concept to the more widely used nuclear magnetic resonance (NMR) spectroscopy [see NMR Overview of Applications in Chemical Biology]. In fact, EPR and NMR are complementary to each other. Both techniques detect magnetic moments, hut NMR determines the chemical stmctures in solution, whereas EPR describes more precisely the electronic and chemical structures of a particular region of the biological system, such as electron transfer centers, metal ions, and an intermediate state of the enzyme or substrate. It is not possible to present a full description of the theory of EPR in an article with this scope. Therefore, only sufficient information is provided here to enable the readers to understand the practical aspects of this analytical tool in enzymology. [Pg.2273]

This volume of Modem Aspects contains a remarkable spread of topics covered in an authoritative manner by some internationally renowned specialists, hi a seminal chapter Drs. Babu, Oldfield and Wieckowski demonstrate eloquently the strength of electrochemical nuclear magnetic resonance (EC-NMR) to study in situ both sides of the electrochemical interface via the simultaneous use of and Pt NMR. This powerful non-invasive technique brings new insights to both fundamental and practical key aspects of electrocatalysis, including the design of better anodes for PEM fuel cells. [Pg.318]

The relationship between the structure and the rheology of polymers is of practical interest for two reasons. First, rheological properties are both very sensitive to certain aspects of the structure and much simpler to use than analytical methods such as gel permeation chromatography and nuclear magnetic resonance. Second, it is the rheological properties that govern the flow behavior of polymers when they are processed in the molten state. [Pg.2]
