VIBRATIONAL SPECTROSCOPY AND 2-DIMENSIONAL STRUCTURE OF MOLECULAR LAYERS ON NACL(100)

We have measured polarized infrared transmission spectra of a variety of molecules physisorbed to NaCl (100). Here we discuss the relation between vibrational spectroscopy of an adsorbate and the geometrical structure of a monomolecular layer. Spectra and proposed structures of CO, CO2, C2H2 and CH4 layers on NaCl (100) are presented as examples.
