Nuclear magnetic resonance (NMR) occurs when atomic nuclei that have spin are placed into a magnetic field; individual spins that are normally random in orientation line up parallel to the magnetic field. NMR is a property that can be used to determine the structure of molecules. Recall that the nucleus has a positive charge because it contains protons that are positively charged and neutrons. Nuclear Magnetic Resonance NMR is based on the behavior of a sample placed in an electromagnet and irradiated with radiofrequency waves: 60 - 900 MHz (l ≈ 0.5 m) The magnet is typically large, strong, $$$, and delivers a stable, uniform field - required for the best NMR data A transceiver antenna, called the NMR probe, is inserted into the center bore of the magnet, an
