Fine structure - Wikipedia
In atomic physics, the fine structure describes the splitting of the spectral lines of atoms due to electron spin and relativistic corrections to the non-relativistic Schrödinger equation.
In these notes we consider the fine structure of hydrogen-like and alkali atoms, which concerns the effects of relativity and spin on the dynamics of the electron. Both these effects are of the same order of magnitude, and must be treated together in …
the fine structure constant and the rest energy of the electron. The fine structure constant is given by α ≡ e2 ~c ≃ 1 137, (2.1.4) and the rest energy of the electron is mc2. Then, e2 a 0 = me4 ~2 = mα2~2c2 ~2 = α2 mc2. (2.1.5) This states that the energy scale of hydrogen bound states is a factor of α2 smaller than
Hydrogen Fine Structure - HyperPhysics
When the familiar red spectral line of the hydrogen spectrum is examined at very high resolution, it is found to be a closely-spaced doublet. This splitting is called fine structure and was one of the first experimental evidences for electron spin.

A proper analysis of fine structure requires solving the relativistic Dirac equation. Here we consider an approach using three perturbations to the Schrödinger Hamiltonian. The first perturbation is a first-order relativistic correction to the kinetic energy operator.
Fine Structure - Explanation, Structure of H Alpha Line and H
The fine structure is the breaking of an atom's primary spectral lines into two or more components, each indicating a slightly different wavelength, in spectroscopy. When an atom transitions from one energy state to another, it produces light, which creates a fine structure.
In this lecture, we will concentrate on the fine structure of the one electron atoms. The cause of this fine structure is the interaction between the orbital angular momentum and the spin angular momentum.

Fine structure, in spectroscopy, the splitting of the main spectral lines of an atom into two or more components, each representing a slightly different wavelength. Fine structure is produced when an atom emits light in making the transition from one energy state to another.
