Infrared spectra of NH3 sorbed on highly dehydroxylated, deuterated, and fluoridated porous glass were recorded. Two pairs of bands at 3409 and 3320cm and at 3350 and 3308cm were attributed to physically adsorbed NH3, hydrogen-bonded to the Si-OH and B-OH groups of the glass surface, resp. Bands at 3368 and 3282cm were ascribed to a triple bond BNH3 complex. Two pairs of bands at 3569 and 3479cm and at 3543 and 3459cm were ascribed to B-NH2 and triple bond Si-NH2 groups, resp. A single band at 3455cm was tentatively assigned to the N-H stretching vibration of a secondary amine, the nitrogen atom being bonded to two surface boron atoms. Author
