Carbon Rings Under Stress (IMAGE) DOE/US Department of Energy Caption A gas-phase X-ray scattering experiment captures cyclopentadiene rapidly transforming into the strained bicyclo[2.1.0]pentene. This structure change is triggered by a pump pulse (blue) and detected through X-ray scattering (yellow).
