    The absorption maximum (maxima is plural of maximum) of a compound is where the compound absorbs UV or visible light the most. This corresponds to the transistion of an electron from the ground state to an excited state one energy level higher, in most cases. Complex compounds can have multiple local absorption maxima, as there are different groups in the same molecule absorbing photons.
