Abstract
Energy transfer at D2O ice/CO/Pt(111) interface under the irradiation of NIR pulses (1064 nm) was studied by time-resolved sum-frequency generation (SFG). When the 140 bilayer (BL)-D2O ice/CO/Pt(111) interface was irradiated, the CO molecules were immediately heated by the energy transfer from the energy-deposited Pt substrate. However, the first 22 BL of ice, which was active for SFG, reached a maximum temperature at 500 ps. It was found that there was a 330 ps of time-response for the energy transfer from the Pt substrate to the first ice layer at the interface.
