WHAT IS NMR

• WHAT DOES NMR STAND FOR?

  nuclear magnetic reasoning
• WHAT IS NMR?

  • magnetic field applied to sample
  • surrounded by source of radio waves and radio receiver
  • generates energy change in nuclei of atoms
  • can be detected
  • electromagnetic energy emitted and interpreted by computer
• HOW IS A MAGNETIC FIELD GENERATED IN SOME ATOMS?

  protons and neutrons spin around the axis

  -> generates magnetic field
