Answer to Question #139492 in Quantum Mechanics for Afraid

Question

Explain multiplicity in spin.

Answer 1

Solution

In atomic phyaics multiplicity in spin is given by

$(2s+1)$

Where s is spin.

For example

If s=1then multiplicity is 3 sometimes this is called triplet state.

Similiarly is s=0 then multiplicity is 1 which is called singlet state.
