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 â¦ In the simplest form of understanding the (a) 1D spectrum is a plot of intensity vs frequency, whereas the (b) 2D NMR spectrum is a plot of intensity vs two independent frequency axes. Magnetic Resonance Spectroscopy: Basic Principles and Selected Applications Sridar Narayanan, PhD ... â¢ An NMR spectrum is a plot of signal intensity versus chemical shift ... 2D (single or multislice) 3D EPI . Execution of a 2D NMR experiment generally involves scanning a series of time-domain signals S(t2), as a function of a t1 time variable which undergoes parametric incrementation throughout independent experiments. Ships from and sold by Basi6 International. The chemical theory that underlies NMR spectroscopy depends on the intrinsic spin of the nucleus involved, described by the quantum number S. Nuclei with a non-zero spin are always associated with a non-zero magnetic moment, as described by Equation \ref{1}, where Î¼ is the magnetic moment, \(S\) is the spin, and Î³ is always non-zero.
