title: Broadband transient dichroism spectroscopy in chiral molecules.
abstract: We perform time-resolved broadband transmission ellipsometry using the ultrafast pump-probe technique in an original setup. Our setup allows us to measure, over a wide spectral range, the optical rotary dispersion of the sample or, when needed, its circular dichroism by adding a broadband quarter-wave plate. While our experiment has been designed to study the transient states in chiral molecules, it performs sufficiently well to also characterize the ground state.
