โฆ Synopsis
The fust hr.&-resoluuon CH stretch vrbrattons m submonolayers of molecules adsorbed on a .smgIe-crysWine surface have been obrained by infrared spectroscopy. lnvo~atron of symmetric and asymmetrrc viiratxonal modes of CH30 adsorbed on Cu(100) jtio%s that rhe molecules are Wed on the surface, that nearest-neqhbour Uttesactlons are mpormnt and that the mtrmuc peak wrdths are large.

The structure of monolayer CH2D2 adsorbed on NaCl ( 100) is explored through the photometry of the polarized infrared spectra. A previous study of CH, on NaCl ( 100) was unable to distinguish between two methane conformations within the monolayer. One conformation is the tripod with three hydrogens
Infrared spectra of adsorbed CO decomposed from HCHO and CH,OH under a constant electrode potential were observed. Oxidation processes of HCHO and CH,OH and the frequency shifts of adsorbed CO are discussed.
