Circular dichroism spectroscopy can determine optical activity in a time-resolved manner, raising the exciting prospect of directly mapping structural changes of important chemical or biological processes involving chiral molecules. Rhee et al. have overcome experimental difficulties to show that optical activity in the infrared can be detected with femtosecond time-resolution by heterodyned spectral interferometry, setting the stage for making 'molecular motion pictures' of fundamental processes from a chiral perspective.
