Femtosecond reaction dynamics in the gas-to-liquid transition region: Observation of a three-phase density dependence

摘要

We report the observation of a striking density dependence in the coherencedynamics of an elementary reaction, solute iodine in solvent rare gases (density from 0 to 50 mol/l). With the help of MD simulations, the time scales of slow and fast solvent‐force fluctuations are resolved and the underlying mechanism is revealed.
