Sub-10 pm Precision
This is the first technology that simultaneously images vibrational wave packets of excited and ground states of water molecules, overcoming the previous limitation of observing only one electronic state at a time, and providing a novel tool for ultrafast molecular dynamics research.

Under current conditions, ROD further extends 9 pm within 2 fs along the ground state of the dication
ROD can stretch more than 50 pm within 5 fs along the autoionisation state of the dication
