Clocking the Movements of Atoms

Roland Piquepaille writes "With special microscopes, scientists and engineers involved in nanotechnologies have been able to 'see' atoms for a while. But they couldn't clock the atomic response to events which typically occur in nanoseconds. Now, U.S. physicists have found a way to clock the movements of atoms at the nanometer scale. In their experiments, they were able to literally watch atoms switching positions in ferroelectric materials. Adding the dimension of time to the observation of the nanoworld could lead to easier developments of 'materials for improved memory applications in microelectronics.'"

In fact attosecond pulses have even been generated, making it possible not only to measure motion of atoms, but motion of electrons within atoms during a chemical reaction.

The article summary is not especially exact, but the structural information (positions of atoms) of this technique is indeed unique. Femtosecond laser spectrscopy will return quite a bit of information, but it doesn't really tell you the movement of the atoms in a bulk sample (only movement of atoms in relation to each other, during the chemical reaction).
