Dynamics of molecular adsorbates exposed to ultrafast thermal gradients
… is bound on one end to a gold film, acting as an ultrafast heat bath. Using a laser flash-heating technique, the heat bath can be jumped to several hundred degrees Celsius in the duration of a few picoseconds. As the energy flows from the thermal reservoir into the molecules com- posing the …

Shock compression and flash-heating of molecular adsorbates on the picosecond time scale
An ultrafast nonlinear coherent laser spectroscopy termed broadband multiplex vibrational sum-frequency generation (SFG) with nonresonant suppression was employed to monitor vibrational transitions of molecular adsorbates on metallic substrates during laser-driven shock compression and …
