Preface
The Nuclear Magnetic Resonance is a very important analytical
method for identifying the structure of organic molecules and
studying solutions that is widely used in diff erent fi elds of modern
science and industry.
The NMR line shape is sensitive to temperature, concentration,
chemical exchange processes and can be successfully used
to study fast reversible reactions. Therefore, NMR has become an
important tool to evaluate the kinetics of reactions at equilibrium
over a wide dynamic range, its results having theoretical and practical
signifi cance. Researchers successfully use molecular dynamics
simulations to determine the time dependent behavior of molecular
systems. NMR investigation of molecules at diff erent concentration
and temperature is often referred to as dynamic nuclear magnetic
resonance. The DNMR investigation of various compounds
in solutions provides valuable information about molecular reorientation,
inter(intra)molecular and spatial interactions, molecular rotations,
formation of molecular association, etc. in the liquid state.
A lot of books and reviews have been devoted to describing the
applications of DNMR in diff erent areas of modern science. Technical
improvements in modern high-fi eld NMR spectro meters
have made it possible to do previously unaccessible DNMR investigations,
so here we demonstrate the role of DNMR in relaxation,
diff usion processes, at determination of molecular weight,
complexations, nanoparticle sizes, etc.
Finally, we believe that the small size of the book and its simplicity
will stimulate further learning of dynamic nuclear magnetic
resonance and its wide application in chemistry, biochemistry,
medicine, molecular physics, etc.
