A Conceptual Introduction to Nuclear Magnetic Resonance (NMR)

  • Observe both Proton and Fluorine Free Precession
  • Discover both the Curie Law and Spin-Lattice Relaxation
  • Measure Spin-Lattice Relaxation as a Function of:
    • Paramagnetic Ion Concentration
    • Viscosity
    • Temperature
  • Observe and Measure Proton-Fluorine J-Coupling
  • Measure Absolute Value of gproton/gfluorine
  • Precisely Measure Earth's Magnetic Field
  • Hear the Precessions on Built-In Audio System
  • Study Bucking Coils for Enhancing Signal-to-Noise
  • Examine Effects of Tuning on Signal-to-Noise
It is hard to imagine a college physics or chemistry major graduating without having performed some kind of magnetic resonance experiment. Nuclear magnetic resonance has been, and clearly will continue to be, an important experimental tool in the arsenal of physicists, chemists, biologists and medical diagnosticians. Recent developments in quantum computing seem to indicate that magnetic resonance might become the basic platform of computer science hardware. There is no doubt that science majors should have a basic understanding of this type of spectroscopy.

TeachSpin, in collaboration with Professor Bill Melton of the University of North Carolina at Charlotte, has developed THE experiment to introduce sophomore, junior, or even senior physics majors to the exciting field of nuclear magnetic resonance (NMR). This new equipment allows students to perform experiments that naturally lead them to an understanding of precession, Curie's Law of paramagnetism, spin-lattice relaxation and even spin-spin coupling. The apparatus lends itself to inquiry based explorations. Its adjustable variables and magnetic resonance signals are all on a human scale. That is, the polarization times are in seconds, and precession frequencies are in the audio range. This significantly enhances the students' connection to the laboratory experience. TeachSpin's Earth's Field Nuclear Magnetic Resonance (NMR) instrument is rapidly becoming a "new classic," replacing the old, enigmatic marginal oscillator.
