Magnetic Resonance: Lecture 8: 7) Nuclear Spin Hamiltonian Dynamics of spins 8) High Resolution NMR of Simple Organic Liquids 8.1 Electronic shielding and chemical shifts 8.2 Chemical shift - Units and reference Standards 8.3 Scalar-Spin-Spin Coupling 8.4 1H NMR Spectroscopy 8.5 Effect of deuteration 8.5 13C Spectroscopy

  2. E Bz 0 Magnetic Resonance Summary A) In a static magnetic field, B =Bzk - Zeeman splitting Energy of the spin For I = 1/2, DE=gBz; Spectroscopy is concerned with changes in spin state by applying electromagnetic radiation. These are induced by absorption or stimulated emission of the electromagnetic photons with energy that matches the Zeeman splitting, DE. DE=gBz =hv

  3. Magnetic Resonance Summary The lines we see in an NMR spectrum correspond to the energy differences of the allowed transitions. NMR spectrum is a plot of frequency versus energy absorption. For a homogeneous system with only one kind of nucleus, we see only a single peak. In real samples the nucleus is influenced by its surroundings.
