Slow photoelectron velocity-map imaging spectroscopy of the phenoxide and thiophenoxide anions
Abstract
High resolution anion photodetachment 2B1 neutral states of both species and to the Ã2B2 state of the thiophenoxy radical. Comparison of the spectra with Franck-Condon simulations allows several gas-phase vibrations to be assigned. The adiabatic electron affinities are determined to be 2.2538(8) eV and 2.3542(6) eV for phenoxy and thiophenoxy, respectively. The term energy of the Ã2B2 state of thiophenoxy is found to be 0.3719(9) eV, higher than the values reported in photodissociation experiments of
