  • frTerme scientifique désignant la structure détaillée des raies spectrales des atomes, due à l'interaction entre le spin de l'électron et son mouvement orbital, ou, plus généralement, la structure interne précise d'un système complexe.

A scientific term referring to the detailed pattern of spectral lines in atoms, caused by the interaction between the electron's spin and its orbital motion, or more generally, the precise internal arrangement of a complex system.

  1. Fine structure in physicsC2formal

    The splitting of spectral lines in atoms due to the interaction between the electron's spin and its orbital motion, as well as relativistic corrections.

    • The fine structure of the hydrogen atom was first explained by Sommerfeld.
    • Physicists use the fine-structure constant to describe the strength of electromagnetic interactions.
    • The fine structure splitting is visible in high-resolution spectroscopy experiments.
