Hi
It is know that the colour exhibited by coordinate compound is because of d-d electron transitions.
These d-d transition lead to absorption of photons of a paticular frequence. AND when a
electron become exited due to absorption of photon it should radiate electromagnetic wave of frequency
corresponding to energy difference between exited and ground state, isn,t it? It would mean that photon
absorbed by electron would be radiate by it at some point of time or instantaneously? But it is said that
colour of coordinate compound which we percive is complementary to the colour absorbed, HOW?
IS it because of the reason that photon that will be randomly radiated by exited electron in all directions
and because of this rate at which that particular photon comes out of coordinate susbstance is very low compared
to the photons of complementary colour which are just simple reflected off from coordinate substance? I am not
sure. I need help !
