  The mid-infrared heating of interfacial water with different initial
temperatures is studied using non-equilibrium 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 configuration
of water molecules at lower initial temperatures. The understanding of the
anomalous phenomenon clarifies the sensitivity of the interfacial properties of
water molecules to the temperature.
