Abstract

Synchrotron-based Far-IR Reflection Absorption Spectroscopy has been used to measure the optical response of multi- layers of water adsorbed on a cleaned and annealed Fe₃O₄(100) single crystal thin film on MgO(100) substrate in the grazing incidence geometry. Several features of the composite system have been observed. In particular, two derivative-type bands at 700 and 800 cm^-1 have been attributed to the librations of ice, and an anti-absorption band at 200 cm^-1 has been assigned to be hindered translations of ice.
