Radiospectroscopy comprises nuclear magnetic resonance nmr electron paramagnetic resonance epr nuclear quadrupolar resonance nqr and some other phenomena the radiospectroscopic methods are widely used for obtaining the information on internal micro and macro structure of objects investigated there are no direct analogues of magnetic relaxation processes among the physical phenomena that define spectra in infrared visible and higher frequency spectroscopy relaxation parameters . Magnetic resonance and its applications chizhik vladimir i chernyshev yuri s donets alexey v frolov vyacheslav v komolkin andrei v shelyapina marina . The book is devoted to the description of the fundamentals in the area of magnetic resonance the book covers two domains radiospectroscopy and quantum radioelectronics radiospectroscopy comprises nuclear magnetic resonance electron paramagnetic resonance nuclear quadrupolar resonance and some other phenomena the radiospectroscopic methods are widely used for obtaining the information on internal nano micro and macro structure of objects quantum radioelectronics which was . Magnetic resonance spectroscopy mrs is a noninvasive tool to measure the chemical composition of tissues in vivo and characterize functional metabolic processes in different parts of the human organs it provides vital biological information at the molecular level
