英文摘要: Low-energy photoelectron imaging of HS2- has been investigated, which provides the vibrational frequencies of the ground state as well as the first excited state of HS2. It allows us to determine more accurate electron affinity of HS2, 1.9080 +/- 0.0018 eV. Combined with Frank-Condon simulation, the vibrational features have been unveiled related to S-S stretching and S-S-H bending modes for the ground state and S-S stretching, S-S-H bending, and S-H stretching modes for the first excited state. Photoelectron angular distributions are mainly characteristic of electron detachment from two different molecular orbitals (MOs) in HS2-. With the aid of accurate electron affinity value of HS2, corresponding thermochemical quantities can be accessed. (C) 2014 AIP Publishing LLC.
