The main content of this thesis is divided into two parts which relate to the two fields of surface science: surface desorption and surface diffusion. In the first part, we have investigated the desorption of diatomic (CO) and polyatomic (NH3, ND3) molecules from Pt(111) surface using femtosecond laser. We find that the femtosecond laser-induced desorption of ammonia is very different from that of carbon monoxide from Pt( 111). The strong laser pulse width dependence of carbon monoxide desorption shows CO desorbs via a hot-electron driven process while NH3(ND3) desorbs by the conventional thermal process even under femtosecond laser irradiation. Little isotope effect between the desorption of NH3 and ND3 also supports our conclusion about a...
