Question

an octahedral complex absorbs radiation of 620 nm. find the crystal field splitting energy

Answer 1

Answer:

$\Delta_o=3.21\times 10^{-19}\ J$

Explanation:

Using the formula for the calculation of crystal field splitting energy as:

$\Delta_o =\dfrac{hc}{\lambda}$

Where,

$\Delta_o$ is the crystal field splitting energy

h is Plank's constant having value $6.626\times 10^{-34}\ Js$

c is the speed of light having value $3\times 10^8\ m/s$

$\lambda$ is the wavelength of the light

Given,

Given, $\lambda=620\ nm=620\times 10^{-9}\ m$

Thus, applying values as:

$\Delta_o=\frac{6.626\times 10^{-34}\times 3\times 10^8}{620\times 10^{-9}}\ J$

$\Delta_o=\frac{10^{-26}\times \:19.878}{10^{-9}\times \:620}\ J$

$\Delta_o=3.21\times 10^{-19}\ J$
