Question

the correct d-electron configuration showing the spin orbit coupling is .....
A. t2g6eg0
b. t2g4eg2
c. t2g4eg0
d. t2g3eg2..​

Answer 1

The d-electron configuration showing the spin orbit coupling is c. t2g4eg0

Definition:

• A phrase for the free ion splits into states of various energies as a result of spin-orbit coupling.
• Spin-orbit coupling only rises as the third power of the primary quantum number n, not as the fourth power of the effective nuclear charge Z.

Effect:

• A one-electron operator that replaces two-electron effects with an effective nuclear charge introduces spin-orbit coupling effects.
• The splits of the components of the lowest energy triplet state are 0.027 and 0.199 cm-1 as a result.
