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

The researchers used a genetic algorithm to obtain the time-varying molecular structure of photoexcited o-nitrophenol from ultrafast electron diffraction data.

However, changes in molecular geometry due to interaction with light…
