Interference fringes, shawin fine structur (splittin) o a cuilit deuterium soorce, viewed throu a Fabry–Pérot interferometer.

I atomic physics, the fine structur descrieves the splittin o the spectral lines o atoms due tae electron spin an relativistic corrections tae the non-relativistic Schrödinger equation. It wis furst meisuret precise-like fur the hydrogen atom bi Albert A. Michelson an Edward W. Morley i 1887,[1] that led tae the theoretical treatment bi Arnold Sommerfeld, that introduced the fine-structur constant.[2]
