One paragraph, so you can see how it reads

CHM391 · UNIT 1 UV- VISIBLE SPECTROSCOPY

Charge - Transfer Absorption: Many inorganic species show charge-transfer absorption and are called charge-transfer complexes. For a complex to demonstrate charge-transfer behaviour, one of its components must have electron donating properties and another component must be able to accept electrons. Absorption of radiation then involves the transfer of an electron from the donor to an orbital associated with the acceptor.
