Popis:	Infrared reflection absorption spectroscopy has been used to study the adsorption and coadsorption of Ga-(C 2 H 5 ) 3 (TEG), NH 3 , and N 2 H 4 at 120-160 K on MgO films grown epitaxially on Mo(100). All three species adsorb molecularly and, upon warming, desorb without leaving any residue detectable by Auger spectroscopy. At submonolayer coverage, NH 3 and N 2 H 4 adsorb in well-defined geometries. NH 3 adsorbs via an Mg-N bond normal to the surface, and N 2 H 4 is suggested to adsorb with one NH 2 forming an Mg-N bond and the other H-bonded to an oxide ion. Evidence is also found for relatively strong TEG-MgO bonding
