Femtosecond-resolved Rydberg states dynamics in chiral molecules

As an important branch of molecular science, time-resolved ultraviolet (UV) spectroscopy promises to address ultrafast photochemical and photobiological processes that play key roles in nature, from ozone photolysis to UV-induced DNA damage [1] , [2] . At the few-femtosecond and attosecond timescales, the study of UV-induced molecular dynamics has been hampered due to the technical challenges for the generation and manipulation of ultrabroadband, few-cycle UV pulses [3] – [5] .
