  • zh科学术语,指原子光谱线因电子自旋与轨道运动相互作用而产生的精细分裂结构;广义上也可指复杂系统的精确内部构造。

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.

    zh精细结构

    • 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.
