摘要：

Partition functions for adsorbed hydrogen atoms have been evaluated for Ni(100), Ni(111), Pd(111) and Pt(111) surfaces. These account for the relative order of magnituted of the preexponential factors for associative desorption, νd, including the abnormally low value for the Pt(111)/H system. Furthermore application of transition state theory yields numbers for νd which are in good agreement with experimental data. © 1979.
