Δ t =(4/9) Δ0 =(4/9) × 18000 cm -1 =8000 cm -1

Q. Crystal Field Splitting Energy (CFSE) for $[C o C l_{6}]^{4 -}$ is $18000 c m^{- 1}$ . The Crystal Field Splitting Energy (CFSE) for $[C o C l_{4}]^{2 -}$ will be

$8000 c m^{- 1}$

$10, 000 c m^{- 1}$

$18, 000 c m^{- 1}$

$16, 000 c m^{- 1}$

$Δ_{t} = \frac{4}{9} Δ_{0}$
$= \frac{4}{9} \times 18000 c m^{- 1}$
$= 8000 c m^{- 1}$
