Dissociative detachment of the fluoroformate anion

Phys Chem Chem Phys. 2020 Dec 16;22(47):27666-27672. doi: 10.1039/d0cp04283h.


Dissociative photodetachment of the FCO2- fluoroformate complex by intense laser pulses is studied using 3D coincidence fragment imaging. The main channels are found to be CO2 + F and FCO + O. Cleavage of the C-F bond is attributed to dissociation on the B[combining tilde]2A1 excited state of the neutral FCO2 radical with significant internal excitation of the molecular fragment, while reductive dissociation of the CO2 moiety is assigned to higher lying states. The measured dissociative ionization products of double-photodetachment are discussed and attributed to intense-laser ionization of dissociative photodetachment products.
