"Their goal is to film events that take place in picoseconds (ps, 10-12 s) or femtoseconds (fs, 10-15 s), with atoms moving mere picometres (a hydrogen atom is roughly 100 pm in diameter). At this resolution, researchers can for the first time directly observe a molecule writhing in slow motion, atomic bonds vibrating and breaking, or even electrons washing back and forth. As these techniques become more mainstream, the pay-offs could be huge."
One of the ideas for using a laser to record a few femtoseconds of a molecule's extremely fast vibrations as it breaks apart came from Kansas State University physicists. Chii-Dong Lin, university distinguished professor of physics, and Anh-Thu Le, research associate professor in James R. Macdonald Laboratory, who are part of an international collaborative project which published in the Oct. 21 issue of Science.
