Question

$\left[Ti\right(NCS{)}_6{]}^{3-}$ ion exhibits a single absorption band at 900 nm. What will be the crystal field splitting energy ( in$kJmo{l}^{-1})$ of the complex?
(Given:$h=6.6\times {10}^{-34}Js;c=3.0\times {10}^{8}m/s;N_A=6.0\times {10}^{23}ions/mole$

Answer 1

We know,
$E={\Delta }_o=h\frac{c}{\lambda }\times N_A$
$=\frac{6.6\times {10}^{-34}\times 3\times {10}^8}{900\times {10}^{-9}}\times 6\times {10}^{23}\times {10}^{-3}\left(kJ/mol\right)$
=$132kJ/mol$
