Electron Spin Resonance
Quantum Mechanics
What we observe is not nature itself, but nature exposed to our method of questioning.
-Werner Heisenberg, Physics and Philosophy, 1963
In this experiment you will use a magnetic field to split the spin states of a free electron. You will then flip these states with radio frequency photons in order to observe electron spin resonance.

This is the power supply that will control the magnetic field. It produces either the top or bottom half of a triangle wave. You may choose the period and amplitude of this signal. |
