Nuclear Magnetic Resonance Spectroscopy

Nuclear magnetic resonance (NMR) is a phenomenon when electromagnetic waves in the MHz range are absorbed in atomic nuclei immersed in external magnetic field and then emitted back at a particular resonant frequency. NMR spectroscopy exploits the NMR related phenomena to obtain useful information about matter at atomic level. In synthetic chemistry, it is applied for structure determination of newly synthesized substances as well as for sample purity checks. In chemical physics, binding and dynamic properties of various systems can be investigated. There are many textbooks dealing with theory of NMR, e.g. Levitt [1], Cavanagh et al. [2], Macomber [3] or Slichter [4]. In this chapter, short introduction to NMR spectroscopy is given as well as detailed treatment of chemical exchange in NMR as described in our paper [5], parts of the text are taken from that publication.
