Oxygen atom: O  (1s22s22p4)

There are 15 different ways to distribute the 4 electrons over de 3 2p orbitals.

This gives rise to 3 atomic states: 3P , 1D (45,2 kcal/mol above) and  1S (95,0 kcal/mol).

Considering spin-orbit coupling, we will have:  3P2, 3P1, 3P0, 1D2 e 1S0.

The  3P1 e  3P0 are 0.453 e 0.668 kcal/mol (228K e 326K) above the ground state, 3P2.

Dear CCLers,

I would like to enquire about the oxygen atom. What is the difference between  the O(3P) and O(1D)?
