摘要：
A velocity map imaging spectrometer was used to investigate the ((X) over tilde (1)A' AuOH + e(-) <- (X) over tilde (2)A' AuOH- +h nu) photodetachment transition at 560 nm. The extracted spectrum shows a well-defined vibrational progression, omega(3)', 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. (C) 2015 Elsevier B.V. All rights reserved.
