![Consider the energy transition of atomic carbon ([He]2s22p²) to one of two
excited energy configurations-either the promotion of an electron from the 2p
atomic orbital ([He]2s22p2) to a) a 3s orbital ([He]2s²2p¹3s¹) termed El or b) to
a 3p orbital ([He]2s22p¹3p¹) termed E2.
Use the five steps in the Russell-Saunders (L-S) coupling scheme to obtain the
states arising for the E2 electronic configuration ([He]2s22p¹3p¹).
The five possible states for atomic carbon are as follows: ³P2,1,0, ¹D2 and ¹So. The
four possible states for E1 energy transitions are ¹P₁, ³P2,1,0. Using Hund's rules,
this information and that from your answer(s) in part (a), label the terms and
states in the energy level diagram provided. (There are two exceptions marked
with a star and the terms and states are included). Justify your choices.
