Abstract

High resolution photoelectron spectra of the vinoxide anion are obtained by slow electron velocity-map imaging. Transitions between the anion X (1)A(') ground electronic state and the radical X (2)A(") and A (2)A(') states are observed. This experiment yields a precise value of 1.8250+/-0.0012 eV for the adiabatic electron affinity and 0.996+/-0.003 eV for the A-X term energy of the vinoxy radical. Franck-Condon simulations of the X (2)A(") <-- X (1)A(') transition are performed at varying levels of approximation. Full treatment with Duschinsky rotation is necessary to reproduce experimental results. Comparison of the experimental and simulated spectra leads to the assignment of previously unresolved transitions, notably between levels of a(") symmetry.
