Abstract

X-Ray photoelectron spectroscopy (XPS) and static secondary ion mass spectroscopy (SSIMS) studies of surface adsorbed H₃AINMe₃ on a SiO₂ substrate support molecular adsorption, most likely as a five coordinate species, H₃AINMe₃(O=), and an aluminium rich species (Al: N 2: 1) sensitive to the amount of exposure to the vapour; ab initio molecular orbital calculations on H₃AINH₃ and H₂O gave formation of H₃AINH₃(OH₂) as energetically favoured by 4.53 kcal mol^-1, and fragmentation of H₃AINH₃(OH₂) to H₃AIOH₂ and NH₃ requiring 13.16 kcal mol^-1 (1 cal = 4.184 J).
