Atomic Term Symbols and Energy Splitting
... The P0, P1, and P2 states are split in energy by a very small amount. This splitting is due to the coupling of spin angular momentum (S) with total orbital angular momentum (L). This spin-orbit coupling splits levels within the same term (that is, the same values of L and S) that have different valu ...
