2025年1月10日 · 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 of
Introduction to NMR - Chemistry LibreTexts
2023年1月30日 · Nuclear Magnetic Resonance (NMR) is a nuclei (Nuclear) specific spectroscopy that has far reaching applications throughout the physical sciences and industry. NMR uses a large magnet (Magnetic) to probe the intrinsic spin properties of atomic nuclei.
Nuclear magnetic resonance spectroscopy - Wikipedia
Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field.
NMR Spectroscopy- Definition, Principle, Steps, Parts, Uses
2022年1月12日 · 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.
NMR is based on the bulk magnetic properties of materials made up of certain isotopes, most notably, protons (11H), but encompassing a wide variety of species including 13C, 19F, and 29Si. NMR is used to measure magnetic fields with exquisite precision.

2023年1月30日 · Nuclear magnetic resonance, NMR, is a physical phenomenon of resonance transition between magnetic energy levels, happening when atomic nuclei are immersed in an external magnetic field and applied an electromagnetic radiation with specific frequency. By detecting the absorption signals, one can acquire NMR spectrum.
Nuclear Magnetic Resonance - an overview - ScienceDirect
Nuclear magnetic resonance (NMR) is the spectroscopy that deals with the phenomenon of a large number of atomic nuclei that possess both magnetic moments and angular momentum when subjected to an external magnetic field.
Nuclear Magnetic Resonance - HyperPhysics
This process is called Nuclear Magnetic Resonance (NMR). A magnetic dipole moment (usually just called "magnetic moment") in a magnetic field will have a potential energy related to its orientation with respect to that field.
