    they involve electronic excitation of electrons to higher lying orbitals using UV/Vis light. other forms of spectroscopy uses other forms of EM waves.

    Most common excitation include

    C=O pi ----> C=O pi*

    n lone pair ---> C=O pi*

    in most organic compounds

    But what actually happens in the spectrophotometer?
    As far as I know it's not mirrors or anything they use, but that might be wrong
