    of molecules of a liquid inside the pores In fact the relaxation times and freezing of the liquid depend on the size of the pores The freezing point curves of the liquid can be easily followed in NMR because the liquid phase and solid phase substances contained in the pores of the signals have very different widths In fact it is possible to correlate relaxation times and freezing curves with the porosity of the system The diffusive properties allow you to have more detailed information involving the size geometry and the interconnection between the pores In particular NMR can measure the mean square displacement x 2 of the solvent molecules as a function of time to get this information on the geometry of the system even if it is of such fractional fractal HETEROGENEOUS SYSTEMS The first source of information on the type of gaming heterogeneous liquid liquid liquid solid liquid solid gas comes from the NMR spectrum allows to estimate the composition and dynamics of each phase Moreover as in the case of porous systems the study of diffusive and relaxation properties of the liquid phase formed information on the structure and dynamics of the system POLYSACCHARIDES The polysaccharides in the presence of water can be dispersed both solutions and gels The composition structure and dynamics of these systems can be studied by HR MAS In particular the gel can be elucidated gellificazione mechanisms through the study of diffusion relaxation and chemical shift These mechanisms are of fundamental importance in various fields such as food pharmaceutical chemical and medical TRANSITION PHASE Most of the phase transitions involve drastic changes in the internal dynamics of the constituents The extent of relaxation times and the shift of NMR lines are useful parameters to follow the phase transformations and to study the

    from the chemical shift The organization of the polymer chains to a larger scale length 20 200A can be measured by exploiting the phenomenon of spin diffusion Since polymers in different environments have different molecular dynamics and hence different NMR relaxation times is possible to study and observe selectively multiphase polymer solid polymer crystalline phase amorphous rubber and interfacial regions In addition some polymers are stable in more than a single conformation and the crystalline solid state NMR provides an effective means to monitor solid solid transitions Aluminum silicon In the study of alumino silicates such as zeolites pozzolana cement ceramics etc spectroscopy joint 17Al 29Si and 23Na provides important information on the crystalline structure and defects in such materials In particular it is possible to evaluate the relationship Si Al symmetry and the degree of coordination of each atom and the composition of the cell POLYSACCHARIDES NMR can study the composition of lignin cellulosic material In particular it is possible to determine the content of cellulose lignin hemicellulose and other polysaccharides present in the fiber and to study the mobility and structure As in the more general case of the polymers can be observed selectively crystalline regions the interfacial amorphous and those that constitute the microfibrils of the fiber plant In addition through the phenomenon of spin diffusion is possible to characterize the extent of micro regions where the cellulose is distributed in the different phases showing the regions in which the polysaccharide is exposed to water COMPOSITE MATERIALS In the case of composite materials is possible to determine the size of the domains of each component consider the type of interaction that exists between them and its dynamics In addition when the composite is made up of both organic and inorganic materials using a variety of nuclei 13C
