Disappearance of the spectrum of the N3UDP-trapped radical translocation product and return of the spectrum of the resting (FeIII)2 cluster upon prolonged incubation on ice. 4.2-K/53-mT Mössbauer spectra of α2β2 with TTP and in the absence or presence of N3UDP. The +N3UDP sample was thawed, incubated on ice, and periodically re-frozen after total incubation times of 10 to 260 minutes for re-acquisition of its Mössbauer spectrum. The spectrum at t = 260 minutes is almost identical to the spectrum of α2β2 with TTP in the absence N3UDP (overlaid as a solid line).
