Abstract
A straightforward calculation reveals a fundamental nonlocality in the lead ing heavy Q (Q) over bar interaction arising from nonperterbative gluon fie ld correlations in the model of a fluctuating QCD vacuum. In light of this, quarkonium spin splitting ratio predictions which have supported the scala r confinement ansatz are reconsidered.
