Nuclear magnetic resonance sohd-state

Two books entitled SoHd-State NMR Techniques and Nuclear Magnetic Resonance Spectroscopy of Cement-Based Materials , have been published. A number of reviews have appeared, entitled Solid-state nuclear magnetic resonance , Solid-state NMR spectroscopy of non-integer spin nuclei , A... 

These ideas have been extended using new analytical techniques, in particular molecular modeling and soHd-state nuclear magnetic resonance (nmr) spectroscopy. 

The melting points, optical rotations, and uv spectral data for selected prostanoids are provided in Table 1. Additional physical properties for the primary PGs have been summarized in the Hterature and the physical methods have been reviewed (47). The molecular conformations of PGE2 and PGA have been determined in the soHd state by x-ray diffraction, and special H and nuclear magnetic resonance (nmr) spectral studies of several PGs have been reported (11,48—53). Mass spectral data have also been compiled (54) (see Mass spectrometry Spectroscopy). 

C Nuclear Magnetic Resonance Spectra. The sohd-state CNMR spectra of 6,7-dimethyl-2,3-di(pyridin-2-yl)quinoxahne (130) and its salts have been used to complement X-ray information (see above) on fine structure. A study of the spectra of mono- to tetramethylquinoxalines has made possible the analysis of mixtures of such methylated quinoxalines obtained from ambiguous primary syntheses.

Framework and Surfaces Since compositions and structures are very diverse, surface and framework properties are also extremely varied. In terms of compositions, coordination, and chemical environments, several methods are particularly informative for the characterization of nanoporous solids, such as nuclear magnetic resonance methods (NMR), UV-visible spectroscopy, Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, x-ray absorption spectroscopies, x-ray photoelectron emission spectroscopy (XPS), and electron paramagnetic resonance (EPR) (4, 6). Among them, sohd state NMR techniques arc largely employed and will be briefly described in the following.

A more powerful tool to determine interaction and bonding types is liquid-state nuclear magnetic resonance (NMR), whatever the nucleus observed, but this method remains difficult because of the insolubihty of the materials formed. However, characterization and determination of modification yields are often determined by liquid NMR of digested sohds. This method can provide useful chemical information, on the basis that the new function is stable under digestion conditions, but there is a critical loss of structural data especially relating to spatial...
