Abstract:The mid-infrared heating of interfacial water with different initial temperatures is studied using nonequilibrium molecular dynamics simulation. It is found that under the irradiation of a pulse at 3360-3380 cm −1 the two-dimensional water monolayer on a hydrophilic surface at a lower initial temperature acquires a much larger temperature jump. The mechanism beneath this counterintuitive phenomenon is the enhanced transition efficiency of the asymmetric OH stretching vibration due to the specific oriented conf… Show more
