Aspirin is not only an important drug but also an interesting physics model system in which molecular vibrations and electrons are coupled in a particular way. For the first time, X-ray experiments in the ultrashort time domain make electron motions visible in real time. They demonstrate that very small atomic displacements shift electrons over much larger distances within the aspirin molecules.
