摘要：

We have studied high-resolution infrared spectra of monolayers of small molecules on single-crystal NaCl (100). Vibrational features contain rich information on the structure and dynamics of the adsorbate array. Thanks to the relative passivity of the substrate, it is appropriate to describe the structure and vibrational motion of the monolayer as if it were a two-dimensional molecular crystal. The corresponding branch of symmetry theory involves 80 “plane groups,” Plane-group analysis has been instrumental to our determination of nontrivial monolayer structures. The structure and spectroscopy of CO2on NaCl (100) will be discussed. © 1990, American Vacuum Society. All rights reserved.
