For many chemical reactions, it remains notoriously difficult to predict and experimentally determine the rates and branching ratios between different reaction channels. This is particularly the case for reactions involving short-lived intermediates, …
As the simplest nitroaromatic compound, nitrobenzene is an interesting model system to explore the rich photochemistry of nitroaromatic compounds. Previous investigations of nitrobenzene's photochemical dynamics have probed structural and electronic …
The dynamics of cyclopentadiene (CP) following optical excitation at 243 nm was investigated by time-resolved pump–probe X-ray scattering using 16.2 keV X-rays at the Linac Coherent Light Source (LCLS). We present the first ultrafast structural …
Identifying multiple rival reaction products and transient species formed during ultrafast photochemical reactions and determining their time-evolving relative populations are key steps toward understanding and predicting photochemical outcomes. Yet, …
Since their discovery more than 100 years ago, X-rays have transformed our understanding of the fundamental structure of matter. They have become an indispensab
The use of relativistic electron pulses at kinetic energies in the megaelectronvolt (MeV) range has revolutionized investigations of ultrafast structural dynami
