Delocalization Effects in Pristine and Oxidized Graphene Substrates... 

The present review summarizes some of the recent results obtained in theoretical studies of pristine and oxidized graphene substrates. It shows that global and local delocalization effects can be seen as a common grounds for explanation of certain peculiar properties of these systems. In the former case it leads to a rationale for the origin of stabilization of diradical singlet states and in the latter case it provides a very simple and intuitive perspective on relative stability of oxyradicals formed. Before discussing these findings in details, it is useful to overview pertinent approaches to the assessment of aromaticity.
