Abstract

The $^{1}Sigma^{+}leftarrow ^{1}Sigma^{+}$ ground state to dipole bound state electronic transition of $mathrm{AlO^{-}}$ has been studied with both rotationally resolved autodetachment spectroscopy and high resolution velocity map imaging photoelectron spectroscopy in a newly constructed apparatus. Vibrational and rotational molecular constants have been determined for both the ground state ($nu^{''}$= 0,1) and excited dipole bound state ($nu^{'}$= 0,1) of the aluminum monoxide anion. The spectra yield the electron binding energy of the dipole bound state, and a more accurate electron affinity for AlO. The photoelectron anisotropies of several transitions were measured. Experimental findings are compared to high level $mathrm{textit{ab initio}}$ calculations. Additionally, high resolution photodetachment imaging of $mathrm{AlO^{-}}$ $^{1}Sigma^{+}$ within energy ranges well above the detachment threshold were measured and compared to previous, low resolution photodetachment results.
