Heterocycles

Nuclear Magnetic Resonance (NMR) is based on the fact that certain nuclei exhibit a magnetic moment, orient by a magnetic field, and absorb characteristic frequencies in the radiofrequency part of the spectrum. The spectral lines of the nuclei are highly influenced by the chemical environment i.e. the structure and interaction of the molecules. NMR is now the leading technique and a powerful tool for the investigation of the structure and interaction of molecules. The present Landolt-Börnstein volume III/35 "Nuclear Magnetic Resonance (NMR) Data" is therefore of major interest to all scientists and engineers who intend to use NMR to study the structure and the binding of molecules. Volume III/35 "NMR-Data" is divided into several subvolumes and parts. Subvolume III/35A contains the nuclei ¹¹B and ³¹P, subvolume III/35B contains the nuclei ¹⁹F and ¹⁵N, subvolume III/35C contains the nucleus ¹H, subvolume III/35D contains the nucleus ¹³C, and subvolume III/35E contains the nucleus ¹⁷O. More nuclei will be presented later.
