Because the stress tensor is not uniquely defined, the bonding indicators originating from the quantum stress tensor may inherit this ambiguity. The cover shows how the bonding analysis of the nitrogen molecule depends on the chosen stress tensor form, as presented by Kati Finzel on page 568(DOI: 10.1002/qua.24618). Along the red lines, the bonding indicators may exhibit critical points. The value of λ, given by the color scale, codes the stress tensor representation, which is needed to form a critical point at exactly that position.
