## Description

 Title: High harmonic generation XUV spectroscopy for studying ultrafast photophysics of coordination complexes Author(s): Ryland, Elizabeth S. Contributor(s): Vura-Weis, Josh; Verkamp, Max A.; Lin, Ming-Fu Subject(s): Instrument/Technique Demonstration Abstract: \newcommand{\midtilde}{\raisebox{-0.25\baselineskip}{\textasciitilde}} Extreme ultraviolet (XUV) spectroscopy is an inner shell technique that probes the M$_{2,3}$-edge excitation of atoms. Absorption of the XUV photon causes a 3p$\rightarrow$3d transition, the energy and shape of which is directly related to the element and ligand environment. This technique is thus element-, oxidation state-, spin state-, and ligand field specific. A process called high-harmonic generation (HHG) enables the production of ultrashort (\midtilde20fs) pulses of collimated XUV photons in a tabletop instrument. This allows transient XUV spectroscopy to be conducted as an in-lab experiment, where it was previously only possible at accelerator-based light sources. Additionally, ultrashort pulses provide the capability for unprecedented time resolution (\midtilde70fs IRF). This technique has the capacity to serve a pivotal role in the study of electron and energy transfer processes in materials and chemical biology. I will present the XUV transient absorption instrument we have built over the past two years, along with preliminary data and simulations of the M$_{2,3}$-edge absorption data of a battery of small inorganic molecules to demonstrate the high specificity of this ultrafast tabletop technique.
