Nuclear magnetic resonance

Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus.This process occurs near resonance, when the oscillation frequency matches the intrinsic. Nuclear magnetic resonance (NMR), selective absorption of very high-frequency radio waves by certain atomic nuclei that are subjected to an appropriately strong stationary magnetic field. This phenomenon was first observed in 1946 by the physicists Felix Bloch and Edward M. Purcell independently o Nuclear Magnetic Resonance. SSNMR resulted essentially for the study of non-sp2 hybridization, functionalization, defects, and other characteristics of carbonaceous materials, such as fullerenes, carbon nanotubes, carbon nanofibers, nanodiamonds, graphene, and graphene oxide, which are important for their wide range of applications [41] Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique to observe local magnetic fields around atomic nuclei.The sample is placed in a magnetic field and the NMR signal is produced by excitation of the nuclei sample with radio waves into nuclear magnetic resonance, which is detected with sensitive.
