Nuclear magnetic resonance spectroscopy is an established technique for studies of stereoselective intermolecular interactions. The application of this technique in combination with CE has been discussed in several review papers (3,4,62,63). In this overview, the potential of NMR spectroscopy is illustrated using just a few examples from the authors own studies. The... [Pg.203]

This article treats the benefits, possibilities and drawbacks of supercritical fluid chromatography (SFC) and supercritical fluid extraction (SFE) coupled to nuclear magnetic resonance spectroscopy. After a general overview and consideration of the motivation for such techniques, the design of high-pressure flow probes, as well as the principle experimental set-ups, are described. By means of several applications and comparison to HPLC-NMR, the utility of these hyphenated techniques is demonstrated. [Pg.195]

Section 2.3.1), nuclear magnetic resonance spectroscopy (NMR, usually as LC-NMR see Section 2.3.2), and less commonly, circular dichroism (CD) or capillary electrophoresis (CE) (Section 2.3.3). A useful overview of these techniques in flavonoid research has been given by de Rijke et al. (2006), and some specific applications in legume chemistry are... [Pg.39]

Characterization is the foundahon for the development and commercialization of new zeolites and zeolite-containing catalysts and adsorbents. Chapter 4 provides an overview of the most commonly employed characterization techniques and emphasizes the uhlity and limitations of each of these methods. An example is provided as to how a multi-technique characterization approach is necessary in order to determine the structure of a newly invented zeolite. Techniques covered in this chapter include X-ray powder diffraction, electron microscopy, infrared (IR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy and physical/ chemical methods.

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 section provides a broad overview of the application of NMR spectroscopy to crystallinity determination in polymers. The approaches illustrated are certainly not exhaustive of those available for the powerful NMR technique and the interested reader is encouraged to consult one or more of the reference books on NMR spectroscopic investigations of polymeric materials (51-53) (see NUCLEAR Magnetic Resonance).

The single most important development in nuclear magnetic resonance (NMR) spectroscopy since the initial observation of the NMR phenomenon in bulk phases in 1945 was undoubtedly the introduction of pulse Fourier transform NMR by Anderson and Ernst. This technique provided greatly increased sensitivity per unit time, making it feasible to obtain spectra for low sensitivity/low abundance nuclei such as More importantly, it allowed the development of a wide variety of sophisticated and powerful multipulse experiments which have revolutionized the use of NMR spectroscopy in studies of molecular structure and dynamics. This article provides an overview of pulse sequence experiments. Many individual experiments are discussed in other articles. [Pg.393]
