Space Quantisation of an Atom
& today I am going to discuss another important topic Electron spin. Without wasting your time let us start…
We donot take s = -1/2 , otherwise S is imaginary which is not possible.
The component of S along magnetic field which is along z-axis.
where, ms is spin-magnetic quantum number which takes 2s + 1 = 2× 1/2 +1 = 2 values.
The gyromagnetic ratio for electron spin is twice the corresponding ratio for electron orbital motion which is e/2m.
Here, “-ve” sign indicates that μs & S are opposite in direction.
