Crystal field splitting energies for octahedral $\left(\Delta_0\right)$ and tetrahedral…

Crystal field splitting energies for octahedral $\left(\Delta_0\right)$ and tetrahedral $\left(\Delta_t\right)$ geometries caused by the same ligands are related through the expression
  1. $\Delta_0=\Delta_t$
  2. $4 \Delta_0=9 \Delta_1$
  3. $9 \Delta_0=4 \Delta_1$
  4. $\Delta_0=2 \Delta_1$

Solution

Octahedral splitting energy $\left(\Delta_0\right)$ and tetrahedral splitting energy $\left(\Delta_t\right)$. For same ligands $ \begin{aligned} \Delta_t & =\frac{4}{9} \Delta_0 \\ 9 \Delta_t & =4 \Delta_0 \end{aligned} $
