Chirality (handedness) is present in all biological systems including photosynthetic complexes. It is an important tool for understanding chemical structure. Yet, we rarely consider chirality in chemical dynamics. Our group has pioneered ultrafast chiral spectroscopies to watch chiral electronic dynamics, memory of chiral excitation, wavepacket collapse, and ultrafast circular dichroism. These experiments reveal new electrodynamics of molecular systems and their interactions.
