Question

Draw the diagram which show the transition of an electron in $\left[Ti\right(H_{2}O{)}_6{]}^{3+}$?

Answer 1

$\left[Ti\right(H_{2}O{)}_6{]}^{3+}$ has $3d^1$ as outer electronic configuration. When energy is supplied, this d electron is transfered from lower $t_{2g}$ level to upper $e_g$ level.
