    NMR APPLICATIONS TO THE SOLID FOSSIL ENERGIES
    Qin Kuangzong, Gou haohui
    Chinese Journal of Magnetic Resonance, 1995, 12(5): 451-458.  
    Abstract     HTML ( )   PDF(497KB)
    This review is concentrated on the NMR appucations to the science and technology of the solid fossil energies.Various solid state NMR techniques such as CP,MAS,DD,DNP,TOSS,CKAMPS,NMRI have been used for the characterization of chemical structure with different parameters in which the aromaticity of carbon and hydrogen is the essential.Recently,new developing techniques of the triple angle MAT and of the spectral editing based on proton multiplicities reveal that more detail structural information may be extracted from the NMR spectra.The topics of NMR application to the solid fossil energies are focused on the natural and artificial thermal evolution mechanism,the oil and gas potential evaluation and the coal property prediction during chemical processing.Sixty-five references have been cited in which twenty-seven are contributed by Chinese authors.
    ACIDIC CENTER OF ZEOLITE AND NMR
    Ding Datong
    Chinese Journal of Magnetic Resonance, 1995, 12(5): 459-464.  
    Abstract     HTML ( )   PDF(420KB)
    The high resolution solid-state NMR is able to determine the framework Si/Al ratio and to analyze the statistical distribution characters of Si,Al atom in the framework of zeolite samples.Based on characterizations of the chemical shift and quadrupole interaction the various aluminum species presented in zeolites can be identified or classified.The microscopic information is helpful to the understanding of acidity mechanisms and provides important basis for researches of the synthesis and the modification of zeolites.
    NMR IN COLLOID AND SURFACE CHEMISTRY
    Du Youru
    Chinese Journal of Magnetic Resonance, 1995, 12(5): 465-471.  
    Abstract     HTML ( )   PDF(443KB)
    The application of NMR and NMR microscopy to surface chemistry is reviewed,The study of adsorption,catalysis and oil recovery by NMR and microscopy is mainly discussed.These facts show that the perspective application of this new technique to the above cited research fields is significant.

    THE NMR SPECTROSCOPY OF TRANSITION METALS
    Chen Zhenzhong, Steve C F. Au-Yeung
    Chinese Journal of Magnetic Resonance, 1995, 12(5): 525-540.  
    Abstract     HTML ( )   PDF(989KB)
    This article reviews the recent devefopment of transition metal NMR spectroscopy with the main emphasis on the methodology for the extraction of chemical information.The discussion is divided into two parts.Solid state NMR focuses mainly in the line shape analysis while the solution part concerns with the interpretation of chemical shifts.
    THE NMR OF TRANSITION METAL COMPOUNDS
    Liu Hanqin
    Chinese Journal of Magnetic Resonance, 1995, 12(5): 541-550.  
    Abstract     HTML ( )   PDF(562KB)
    Transition metal elements form various structural types of coordination and cluster compounds.Due to their outer d or f orbital and nudear magnetic spin,transition metal moleculare give very rich infoimation in their NMR spectra.Center nietal and ligand element NMR of transition metal molecule are discussed.Magnetic susceptibility of the compound can be measured by NMR method.Information of magnetochemistry and other spectrochemistry enable us to understand the synergism within a transition metal moleculer.
