The fine structure constant is also known as Sommerfeld's constant. And it is a dimensionless physical quantity that can be expressed in terms of other fundamental physical constants.<br>For more information on this concept, kindly visit our article at;<br>https://jayamchemistrylearners.blogspot.com/2022/04/bohr-sommerfeld-model-chemistrylearners.html

Physical interpretation of the fine structure constant α It determines the size of fine- structure splitting of the hydrogen spectrum. The Greek letter α (alpha) is used to symbolize it. It is a constant fundamental physical quantity introduced by the German physicist Arnold Sommerfeld in 1916 1916 It quantifies the electromagnetic interaction of the electrically charged elementary particles and the photon (light radiation). For that, he conceptualized α as a quantity with no physical dimension having the SI unit of measurement of 1, which we call dimensionless quantity. So, α is purely a number with a value equal to 1/137, independent of the system of units. α= 1/137 It can be interpreted with the help of the following four physical quantities. They are The fine structure constant in terms of Bohr radius α expressed in terms of the Vacuum impedance α expressed in terms of Electron's potential energy α expressed in terms of Planck's constant Blog:https://jayamchemistrylearners.blogspot.com/
