Title: The Application of the FPD Method on the Anion Photoelectron Spectra for ThS2- and ThSO-
Abstract: The Feller-Peterson-Dixon (FPD) method is a flexible composite approach that can be adapted to determine energetic properties such as ionization potentials (IPs) and electron affinities (EAs), among others. It has no fixed prescription, and can be applied to either atoms or molecules. Beyond previously applying it to re-evaluate outdated or inaccurate IPs of Np, Pu, Am, and Cm, as well as to clarify the ground state of each of their oxidation states, more recently, it has been applied in support of the gas-phase Anion Photoelectron Spectroscopy work of Kit Bowen et al. over at Johns Hopkins University to assist in understanding ThS2 and ThSO.
Initially, our group calculated the adiabatic electron affinity and vertical detachment energy for these molecules to determine which of these aligned with the strongest peak in each anion spectrum. Now, we are applying the FPD method to examine the most likely geometries and low-lying excited states of these molecules in order to potentially clarify what the remainder of these spectra could indicate.
