What is the relationship between observed colour of the complex and the wavelength of light absorbed by the complex?
Advertisements
उत्तर
When white light falls on the complex, some part of it is absorbed. Higher the crystal field splitting, lower will be the wavelength absorbed by the complex. The observed colour of complex is the colour generated from the wavelength left over.
