It is not currently known if it [alpha] can be derived from
first principals in terms of mathematical constants, but it can be
determined as a conglomeration of the electron charge e, (h-bar),
and the speed of light c.>>

The quantity , which is equal to the ratio v1/c where v1 is the velocity
of the electron in the first circular Bohr orbit and c is the speed of light
in vacuum, appeared naturally in Sommerfeld's analysis and determined
the size of the splitting or fine-structure of the hydrogenic spectral lines.
Sommerfeld's theory had some early success in explaining experimental
observations but could not accommodate the discovery of electron
spin. Although the Dirac relativistic theory of the electron introduced
in 1928 solves the main aspects of the problem of the hydrogen
fine-structure, still determines its size as in the Sommerfeld theory.
Consequently, the name "fine-structure" constant for the group of
constants below has remained:
