Credit: Lixin He and Pengfei LanResearchers developed a method to measure charge migration speed in molecules, discovering it can move several angstroms per femtosecond. The study provides insights into ultrafast molecular dynamics and potential chemical reaction control.
Experimentally, the sensitive dependence of CM on molecular orbitals and orientations has made the CM dynamics complex and difficult to trace. There are still some open questions about molecular CM that remain unclear.
, a research team from Huazhong University of Science and Technology , in cooperation with theoretical teams from Kansas State University and University of Connecticut, recently proposed a high harmonic spectroscopy method for measuring the CM speed in a carbon-chain molecule, butadiyne . Corresponding author Pengfei Lan, a professor in the HUST School of Physics, remarks, “This work provides deep insight into CM dynamics in molecules and could strengthen our understanding of these ultrafast dynamics.”

New experimental research measures the speed of molecular charge migration for the first timeTo discover how light interacts with molecules, the first step is to follow electron dynamics, which evolve at the attosecond timescale. The dynamics of this first step have been called charge migration (CM). CM plays a fundamental role in chemical reactions and biological functions associated with light–matter interaction. For years, visualizing CM at the natural timescale of electrons has been a formidable challenge in ultrafast science due to the ultrafine spatial (angstrom) and ultrafast temporal (attosecond) resolution required.
