Using a new ultrafast camera, researchers have recorded the first real-time image of two atoms vibrating in a molecule.
The team used ultrafast laser pulses to knock one electron out of its natural orbit in a molecule. The electron then fell back toward the molecule scattered off of it, analogous to the way a flash of light scatters around an object, or a water ripple scatters in a pond.
Researchers at Ohio State University and Kansas State University have captured the first-ever images of atoms moving in a molecule. Shown here is molecular nitrogen. The researchers used an ultrafast laser to knock one electron from the molecule, and recorded the diffraction pattern that was created when the electron scattered off the molecule. The image highlights any changes the molecule went through during the time between laser pulses: one quadrillionth of a second. The constituent atoms’ movement is shown as a measure of increasing angular momentum, on a scale from dark blue to pink, with pink showing the region of greatest momentum.
