{wiki=Fine_electronic_structure}

The term "fine electronic structure" generally refers to the detailed arrangement of electrons in an atom or molecule and how this arrangement affects the physical and chemical properties of the system. In quantum mechanics and atomic physics, electronic structure involves the distribution of electrons around nuclei and the energy levels they occupy. However, the phrase "fine electronic structure" is often associated with concepts in atomic physics, particularly in relation to fine structure splitting.
