A long-predicted ultrafast isomerization in the UV photochemistry of bromoform is visualized for the first time by femtosecond time-resolved electron diffraction. At 267 nm excitation, the reaction pathway surpasses direct dissociation by a 60:40 margin.

Bromoform Molecules Like to Rearrange Their Atoms

Ultrafast electron diffraction imaging reveals atomic rearrangements long suspected to be crucial in the photochemistry of bromoform.

Researchers retrieved the time-varying molecular structure of photoexcited o-nitrophenol from ultrafast electron diffraction data using a genetic algorithm

Speedy Nuclei Do the Twist

Ultrafast electron imaging captures never-before-seen nuclear motions in hydrocarbon molecules excited by light.
