MCQ
Who discovered spin quantum number
  • Unlenbeck and Goudsmit
  • B
    Nell’s Bohr
  • C
    Zeeman
  • D
    Sommerfield

Answer

Correct option: A.
Unlenbeck and Goudsmit
a
George Unlenbeck and Samuel Goudsmit were studying certain details of spectral lines known as the anamalous Zeeman effect. This eventually led them to the realization that Pouli's fourth quantum number must relate to electron spin.
