Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful experimental methods available for atomic and molecular level structure elucidation. It is a powerful technique in that it is a noninvasive probe that can be used to identify individual compounds, aid in determining structures of large macromolecules, such as proteins, and examine the kinetics of certain reactions.

d) A labelled sample of a known biosynthetic precursor is fed to a culture. An alkylating agent is added some time later that reacts with any labelled biosynthetic intermediate that might have been formed, and prevents it from being converted to the fnal product.

Nuclear Magnetic Resonance Spectroscopy • When a charged particle such as a proton spins on its axis, it creates a magnetic field. Thus, the nucleus can be considered to be a tiny bar magnet. • Normally, these tiny bar magnets are randomly oriented in space. However, in the presence of a magnetic field B.

There are innumerable books written about NMR. Many of these avoid any serious attempt to describe how the experiments work, but rather concentrate on the interpretation of various kinds of spectra. An excellent example of this kind of book is J. Sanders and B. Hunter Modern NMR Spectroscopy.

Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful and widely used techniques in chemical research for investigating structures and dynamics of molecules. Advanced methods can even be utilized for structure determinations of biopolymers, for example proteins or nucleic acids.

NMR is also used in medicine for magnetic resonance imaging (MRI). The field of nuclear magnetic resonance has experienced a number of spectacular developments during the last decade.
