摘要：

High-quality ab initio computational results for the interaction of N2O with the silanol molecule H3SiOH, taken as representative of the isolated hydroxyl at the silica surface, are compared with IR data concerning the real system measured at 195 K. Besides a non-specific interaction, features typical of hydrogen bonding are observed: two types of complexes are formed simultaneously, differing in their 2nu1 mode, probably one nitrogen-bonded, the other oxygen-bonded. Ab initio results are in excellent agreement as far as binding energies are concerned: the two complexes show comparable stabilities, once electron correlation has been taken into account; however, SCF-calculated IR features do not allow a definite vibrational assignment of the two complexes.
