Since these interactions lead to donation of occupancy from the localized NBOs of the idealized Lewis structure into the empty non-Lewis orbitals (and thus, to departures from the idealized Lewis structure description), they (Table are referred to as "delocalization" corrections to the zeroth-order natural Lewis structure.
