Q. Show example of electromagnetic radiation?
When light associated with energy hv, such that D0. = hv, is passed through a solution of [Ti(H20)6]3+, absorption of light takes place and the lone electron from ground state is raised to the excited state. Experimentally, it is found that the energy for this absorption is around 20,400 cm-1Hence, we can write D0= 20,400 cm-1 and CFSE = -2/5 x 20,400 or -8,160 cm-1 or approximately 98 kJ mol-1.
