A window on molecular chirality at the timescale of electron motion
A laser technique, which has a time resolution of only a few femtoseconds, captures how photoexcited electrons can influence the chirality — or handedness — of neutral molecules. The resulting helical currents could be used to control physical and chemical properties that result from chiral interactions. This technology could have applications in fields ranging from solid-state electronics to drug design.
