摘要：

The infrared spectrum of alkyl groups on Al(100) derived from the dissociative adsorption of tri-isobutylaluminum (TIBA) or 1-iodobutane are studied as a function of surface temperature. Once formed, these species maintain both their structure and orientation on the surface to temperatures in excess of 500 K. An upper bound for the activation energy to cleave the Al-C bond in adsorbed TIBA is estimated to be approximately 13 kcal/mol.
