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.
我们使用超快泵浦-探测技术在原始设置中进行了时间分辨宽带透射椭圆偏振测量。我们的设置允许我们通过添加宽带四分之一波片，在很宽的光谱范围内测量样品的旋光色散，或者在需要时测量其圆二色性。虽然我们的实验旨在研究手性分子的瞬态态，但它的表现足以很好地描述基态。
