I Localized and delocalized states, meaning? in Organics

  1. Apr 5, 2016 #1
    Looking (if possible for some of you) a concise but non mathematical explanation of the terms localization and delocalization?
    This questions is related to Quantum Molecular Physics. When reading a paper of Spectroscopy and allowed transitions, I encounter the following phrase " [Intersystem Crossing]... between Charge Transfer state and locally excited state ...". So for sake of argument, let's assume that we are not talking about especific states e.g. charged or excited, but that we are discussing different eigenstates of simple system (not necessarily H atom or alike), at least one system that can have delocalized and localized states, is that possible? what do these terms mean physically? Thanks in advance
