Structural information on electronically excited neutral molecules can be indirectly retrieved, largely through pump–probe and rotational spectroscopy measurements with the aid of calculations. Here, we demonstrate the direct structural retrieval o

Visualizing chemical reactions as they occur requires atomic spatial and femtosecond temporal resolution. Here, we report imaging of the molecular structure of acetylene (C 2 H 2 ) 9 femtoseconds after ionization. Using mid-infrared laser–induced e

Laser-induced electron diffraction is an evolving tabletop method, which aims to image ultrafast structural changes in gas-phase polyatomic molecules with sub-{\AA}ngstr\"om spatial and femtosecond temporal resolution. Here, we provide the general fo

We report the simultaneous retrieval of multiple bond lengths of the polyatomic molecule C 2 H 2 by coherent “self-electron” wave packets generated by the interaction of the molecular target with intense mid-IR laser pulses [1].

We present accurate extraction of multiple bond lengths for aligned and anti-aligned C2H2 using recollision electron diffraction. We measure bond lengths of1.20±0.06A (C≡C) and 1.06±0.08A (C-H).
