This video part 1 accompanies the Nuclear Magnetic Resonance Experiment, providing students with an introduction to the theory, apparatus, and procedures.
In the NMR experiment, nuclear dipoles (the samples) are subjected to a static magnetic field of about 4000 gauss as well as a time-varying radio-frequency magnetic field perpendicular to the static field. The static field causes Zeeman-effect splitting between sub-states, and the radio frequency field is tuned to the Larmor frequency so that it induces transitions between the sub-states. The resonance condition is observed using the Bloch two-coil induction technique. You will observe proton and fluorine nuclei. You will learn techniques of lock-in detection and signal averaging.
