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).
