Elucidating Norrish Type-I reactive pathways by ultrafast X-ray absorption spectroscopy

Martin Graßl, Pablo Unzueta, Andreas E. Hillers-Bendtsen +20

Norrish type I reactions selectively cleave carbon-carbon bonds directly adjacent to carbonyl groups. Despite their broad use in combination with aromatic carbonyls for additive ma…

Covariance Analysis of Impulsive Streaking

Jun Wang, Zhaoheng Guo, Erik Isele +4

We present a comprehensive framework of modeling covariance in angular streaking experiments. Within the impulsive streaking regime, the displacement of electron momentum distribut…

Attosecond Coherent Electron Motion in a Photoionized Aromatic Molecule

Taran Driver, Zhaoheng Guo, Erik Isele +50

In molecular systems, the ultrafast motion of electrons initiates the process of chemical change. Tracking this electronic motion across molecules requires coupling attosecond time…

"Beam `a la carte": laser heater shaping for attosecond pulses in a multiplexed x-ray free-electron laser

Siqi Li, Zhen Zhang, Shawn Alverson +19

Electron beam shaping allows the control of the temporal properties of x-ray free-electron laser pulses from femtosecond to attosecond timescales. Here we demonstrate the use of a…

Attosecond Delays in X-ray Molecular Ionization

Taran Driver, Miles Mountney, Jun Wang +34

The photoelectric effect is not truly instantaneous, but exhibits attosecond delays that can reveal complex molecular dynamics. Sub-femtosecond duration light pulses provide the re…

Effect of Dimensionality on the Optical Absorption Properties of CsPbI Perovskite Nanocrystals

Albert Liu, Luiz G. Bonato, Francesco Sessa +7

The band-gaps of CsPbI perovskite nanocrystals are measured by absorption spectroscopy at cryogenic temperatures. Anomalous band-gap shifts are observed in CsPbI nanocubes…
