The femtosecond m-edge approach to the photodynamics of iron(II) complexes
… these capabilities to investigate the ultrafast photodynamics of low-spin iron(II) complexes. We first tackle the challenges associated with interpreting the L2,3-/M2,3-edge spectra of excited state species. The L2,3-/M2,3-edge spectra of transition metal species are conventionally modelled using …

Investigations of Ice Photodynamics: Molecular Dynamics Studies and an Apparatus for Solid Sample Velocity Map Imaging
… Dynamics (MD) simulations applied to investigate photodynamics in amorphous solid water (ASW), ice XI, and ice Ih. Additionally, results from a velocity map imaging apparatus, which has been augmented for the study of low temperature solid samples, are presented. Specifically, preliminary results …

Nonadiabatic Dynamics of Cis-Trans Photoisomerization --- a First Principles Study
… algorithm has been developed to simulate photodynamics. This method can simulate the full time-dependent wavefunction of molecules with tens of atoms. AIMS data can be directly compared to the results of ultrafast time-resolved photoelectron spectroscopy data. This allows both the …

Photophysics of Phenylene Vinylene Polymers and Oligomers: The Influence of Nanocrystalline Domains
… looks at the nature of excited states and their photodynamics in phenylene vinylene molecules. Poly-p-(phenylene vinylene) (PPV), poly[(2-methoxy-5-hexyloxy-p-phenylene)vinylene] (MH-PPV), and 1,4-distyrylbenzene (DSB), a small molecule analog of PPV, are studied using various spectroscopic …

Ultrafast photophysics of transition metal coordination complexes studied with femtosecond extreme ultraviolet transient absorption spectroscopy
… The relation of function to metal-specific photodynamics will help lay essential groundwork for the development of multimetallic catalysts with efficiencies comparable to those found in nature.

Ultrafast spatiotemporal dynamics of photoexcitations in two-dimensional semiconductors
… at low excitation densities. We find that the photodynamics are largely dominated by the screening of the Coulomb interaction by excited states. At high excitation densities, when the screening of the Coulomb interaction is such that the excitons are no longer stable, we observe their complete …
