Abstract
The interactions occurring between MgO(100) surface and small molecules such as methanol, water, and acetic acid were analyzed using transmission Fourier transform infrared (FTIR) spectroscopy in conjecture with atomic force microscopy (AFM). About 15-20 crystals, cleaved along (100) faces of MgO under dry nitrogen purge, were stacked in cylindrical sample cell for spectroscopic measurements. The InSb detector was also used, coupled with CaF 2 windows, which limits frequency range of FTIR spectra collected to 4500-1800 cm -1. The results show that reactivity of MgO(100) surface to adsorbates is directly related to acidity of molecule.
