    A velocity map imaging spectrometer was used to investigate the (X1A AuOH+e-←X2A AuOH-+hν) photodetachment transition at 560 nm. The extracted spectrum shows a well-defined vibrational progression, ω3′, with a frequency of 567(5) cm-1. The adiabatic electron affinity is assigned to 1.695(5) eV and the presence of a vibrational hot band allows the determination of the corresponding anion frequency to 431(20) cm-1. This represents a re-assignment of the photoelectron spectrum previously reported by Zheng et al. [1]. A Franck-Condon simulation based on coupled cluster calculations is in excellent agreement with the observed vibronic progression.
