Ground state term symbol for d7 complexes
Accepted Answer
The ground state term symbol for d7 complexes depends on whether the complex is high spin or low spin. Here's how to determine it:
1. High Spin (Weak Field Ligands):
In a high spin d7 complex, the electrons fill the orbitals according to Hund's rule, maximizing spin multiplicity.
The configuration is t2g^5 eg^2.
S = 3/2 (total spin) and L = 2 (total orbital angular momentum)
The term symbol is ^4F
2. Low Spin (Strong Field Ligands):
In a low spin d7 complex, electrons pair up in the lower energy orbitals before filling the higher energy orbitals.
The configuration is t2g^6 eg^1.
S = 1/2 (total spin) and L = 1 (total orbital angular momentum)
The term symbol is ^2D
