  • Water vibrational motion, which occurs on the few-femtosecond timescale and underpins energy transfer within the hydrogen bonding network, has remained challenging to observe in real time due to constraints in time resolution. Here, the authors investigate the ground state vibrational dynamics of liquid water using a sub-5 fs near-infrared pump pulse and few-fs ultraviolet probe pulses, observing rapid dephasing of the OH stretch mode that precedes its relaxation via coupling to the bend modes.

  • Time-resolved photoelectron circular dichroism with a temporal resolution of 2.9 fs is used to track the ultrafast electron dynamics following ultraviolet excitation of neutral chiral molecules, which generate chiral currents that exhibit periodic rotation direction reversal.

  • The authors investigate the ultrafast dissociative dynamics of iodomethane induced by sudden ultraviolet photoexcitation. They showcase how subsequent ionization within a 5-femtosecond window can stabilize the molecule and prevent fragmentation.

  • Femto-chemistry allows researchers to probe the individual transitions in a molecule during a chemical reaction. Here, the authors show that a relatively simple tabletop experiment is capable of capturing the dynamics of isomerization and fragmentation of the acetylene cation to record a molecular movie.

  • Sudden ionisation of larger molecules can initiate a correlation-driven process called charge migration, but due to its short time scale this process is challenging to observe. Here, the authors ionise adenine with extreme ultraviolet light and observe electron correlation in the molecule at the attosecond scale in real-time.
