Detection of Spin
When lines of the hydrogen spectrum are examined at very high resolution, they are found to be closely spaced doublets. This splitting is called fine structure, and was one of the first experimental evidences for electron spin. The direct observation of the electron's intrinsic angular momentum was achieved in the Stern–Gerlach experiment.

Famous quotes containing the word spin:
“In tragic life, God wot,
No villain need be! Passions spin the plot:
We are betrayed by what is false within.”
