It appears to be in some ways more akin to tunneling electron microscopy. The molecule has a sort of "quantum atmosphere" that can be proved by its quantum effects. I had thought some years ago it was possible to probe this with how it destructively interferes a quantum wave. This appears to border on that sort of physics.
I was once asked how a quantum particle interacted with a quantum barrier. It is the standard QM problem to compute the amplitude of a quantum wave impacting a potential barrier. The question pertained to how does this happen; is it some sort of interaction. I figured it was destructive interference with the quantum atmosphere of the barrier, at least for the so called infinite potential barrier, where for the finite barrier the destructive interference is not complete.
