Interference fringes, showing fine structure (splitting) of a cooled deuterium source, viewed through a Fabry–Pérot interferometer.

In atomic physics, tha fine structure describes the splitting of the spectral lines of atoms due tae electron spin and relativistic corrections to the non-relativistic Schrödinger equation. It was first meisuret precisely fer tha hydrogen atom by Albert A. Michelson and Edward W. Morley in 1887,[1] whilk led tae tha theoretical treatment by Arnold Sommerfeld, who introduicet tha fine-structur constant.[2]
