Abstract

Chiral molecules, the movie Chiral molecules interact differently with left and right circularly polarized light, and the resultant optical activity has long been used to learn about molecular structures. The development of circular dichroism spectroscopy that can determine optical activity in a time-resolved manner raises the exciting prospect of the direct mapping of structural changes of important chemical or biological processes involving chiral molecules. Rhee et al. show that despite the difficulties posed by notoriously weak signals and large background contributions, optical activity in the infrared can be detected with femtosecond time-resolution by heterodyned spectral interferometry. This means that 'molecular motion pictures' of fundamental processes from a chiral perspective could soon be a reality.
