Abstract:The phenoxide anion (C$_{6}$H$_{5}$O$^{–}$), with a large dipole moment of 4.0 D for its neutral core, can support an excited dipole-bound state (DBS) 97 \wn below the electron detachment threhold [Liu et al. Angew. Chem. Int. Ed. 52, 8976-8979 (2013)]. The vibrational mode-specific autodetachments from the vibrational levels of the DBS were first discovered in this system by high-resolution resonant photoelectron (PE) imaging. Here, we report a photodetachment spectrum of the phenoxide anion up to 2000 \wn above the detachment threshold. Several new vibrational peaks are observed due to autodetachment from combinational levels of the DBS. The corresponding resonant PE spectra show a clear peak due to the lowest-frequency bending mode, suggesting the possibility of a slight nonplanar structure for the phenoxy radical.
