The NMR phenomenon relies on the interaction of the nuclei of certain atomic isotopes with a static magnetic field. This magnetic field makes the possible spin-states of the nucleus differ in energy, and using NMR techniques the spins can be made to create observable transitions between the spin states. Common NMR active nuclei are 1H, 13C, 31P ...

The first NMR spectrum was first published in the same issue of the Physical Review in January 1946. Bloch and Purcell were jointly awarded the 1952 Nobel Prize in Physics for their research of Nuclear Magnetic Resonance Spectroscopy. Nuclear magnetic resonance (NMR) spectroscopy is a crucial analytical tool for organic chemists.

Since the first observation of nuclear magnetic resonance (NMR) phenomenon by E. M. Purcell [] and F. Bloch [] in 1946, it has made a strong impact in a wide range of fields of fundamental and applied science.Nowadays, NMR spectroscopy is, inarguably, an indispensable and powerful method for scientists in the area of material …

G-quadruplexes (G4s) are noncanonical nucleic acid secondary structures with diverse topological features and biological roles. Human telomeric (Htelo) overhangs consisting of TTAGGG repeats can fold into G4s that adopt different topologies under physiological conditions. These G4s are potential targets for anticancer drugs. Despite …

Nuclear magnetic moments are of the order of a nuclear magneton. μ N = eℏ 2M = 5.051 ×10−27JT−1 (14.7) (14.7) μ → N = e ℏ 2 M = 5.051 × 10 − 27 J T − 1. where M is the mass of the proton. The nuclear magneton is smaller than the Bohr magneton by a factor m/M ≈ 1836. Table 1: Some common nuclei in NMR spectroscopy.

Nuclear magnetic resonance spectroscopy. Nuclear magnetization is generated by the interaction of nuclear spins with a magnetic field. Only some isotopes, determined by the number of protons and neutrons, possess a property called 'spin', rendering them 'NMR active', including e.g. 1 H, 13 C, and 31 P.
