Fine structure constant

To account for the amount of splitting of spectral lines, Sommerfeld entailed a term that he named fine structure constant. In Sommerfeld's analysis, it was the ratio of the electron's velocity in the ground state of the relativistic Bohr atom to the speed of the light in the vacuum. And he used the Greek letter u03b1 (alpha) to symbolize it. <br><br>For more information on fine structure constant topic, kindly refer our article at;<br>https://jayamchemistrylearners.blogspot.com/2022/04/bohr-sommerfeld-model-chemistrylearners.html

  1. FINE STRUCTURE CONSTANT It determines the size of fine-structure splitting of the hydrogen spectrum. OVERVIEW It is also renowned as the Sommerfeld constant. So, its name signifies that it is a constant quantity introduced by the German physicist Arnold Sommerfeld in 1916 SIGNIFICANCE It is a dimensionless physical quantity that accurately express the gap in the energy difference between the coarse and fine structures of the spectral lines in the hydrogen atom. The Greek letter α (alpha) is used to symbolize it. FORMULA In Sommerfeld's analysis, it was the ratio of the electron's velocity in the ground state of the relativistic Bohr atom to the speed of the light in the vacuum. VALUE α is purely a number with a value equal to 1/137, independent of the system of units. CONCLUSION It is the coupling constant that quantifies the electromagnetic interaction of the electrically charged elementary particles and the photon (light radiation).
