About the Cover

Cover Figure


COVER X-rays emerge with varying intensity (red/green wave) as an electron is pulled out of and then pushed back into a vibrating N2O4 molecule by an intense laser field. The pattern reveals real-time dynamic changes in electronic spatial configurations, or orbitals, at the compressed (left blue orbital) and stretched (right blue orbital) limits of the vibration cycle.
