    • (b) Energy minima: UCCSD(T)/cc-pVTZ. Transition states: UCCSD-(T)/cc-pVTZ//UCCSD(T)/cc-pVDZ. The C-O bond distance in the TS for formation of E-FCOOO is calculated as R = 2.14 Å. The TS is calculated to be almost planar. (E) refers to E-fluoroformylperoxy or to its TS of formation, and (Z) refers to Z-fluoroformylperoxy or to its TS of formation.

    • -1) should have been readily detectable in our experiments, and monomeric FCOOH in acetonitrile solution is unlikely to have a lifetime in the low microsecond range only. Furthermore, decay of FCOOH would have to be coupled to a secondary formation of carbon dioxide, which we do not observe.

    • 2 extrusion would have to occur via a strained transition state involving a four-membered ring, which appears unlikely. The formation of FCOOO in a vibrationally hot state that rapidly decarboxylates appears more plausible.

    • 2 is higher than the intensity of the CO band by a factor of ca. 8. The absorption of CO thus remains hidden in the experimental noise.
