https://jmnr.sciforce.org/JMNR <p>Journal of Nuclear Magnetic Resonance (NMR) Spectroscopy JNMR of Sciforce Publications is broad field of Analytical Chemistry and its related fields Nuclear Magnetic Resonance (NMR) Spectroscopy, structural analysis of organic molecules and inorganic molecules. JNMR publishes original research articles, book chapters reviews, short communications, rapid communications, and abstracts. Nuclear magnetic resonance (NMR) spectroscopy 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 therefore not involving electromagnetic waves and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus. All isotopes that contain an odd number of protons and/or neutrons (see Isotope) have an intrinsic nuclear magnetic moment and angular momentum, in other words a nonzero nuclear spin, while all nuclides with even numbers of both have a total spin of zero. The most commonly used nuclei are H1 and C13 although isotopes of many other elements can be studied by high-field NMR spectroscopy as well. This process occurs near resonance, when the oscillation frequency matches the intrinsic frequency of the nuclei, which depends on the strength of the static magnetic field, the chemical environment, and the magnetic properties of the isotope involved; in practical applications with static magnetic fields up to ca. 20 tesla, the frequency is with (60–1000 MHz). NMR results from specific magnetic properties of certain atomic nuclei. Nuclear magnetic resonance spectroscopy is widely used to determine the structure of organic molecules in solution and study molecular physics, crystals as well as non-crystalline materials. NMR is also routinely used in advanced medical imaging techniques, such as in magnetic resonance imaging (MRI).</p> en-US Mon, 20 Sep 2021 20:01:28 +0000 OJS 3.2.1.4 http://blogs.law.harvard.edu/tech/rss 60
