Formula: $$\mu = \sqrt{n(n + 2)} \quad \text{BM}$$
Concept: Relates the hybridization and pairing outcome of VBT directly to the complex's experimental magnetic behavior, calculating the total magnetic contribution solely from unpaired electron spins.
Notation:
- $$\mu$$ = Spin-only magnetic moment in Bohr Magnetons (BM);
- $$n$$ = Number of unpaired electrons present in the metal ion's valence shell.
