Abstract

oxidase. Laser-induced EPR and DFT reveal a semiquinone radical electronically isolated from Cu(II) by orthogonal orbital alignment. The weak magnetic exchange underscores how geometry governs coupling, providing insight into transient states of metalloenzymes and their synthetic analogues.
