• dependence renders this option again unlikely because rather three photons of 333 nm would be expected to be required to excite CH3Br− to CH3Br+. The A-band of the free methyl bromide molecule has its maximum absorption cross section at around 6.2 eV [3]. The observation that CH3Br adsorbed on Au can be

• (energy dependent) intensity of incident X-rays and μ is the absorption coefficient. Since for photon energies below 20 keV the photoeffect dominates over Raleigh and Compton scattering, μ can be approximated by the photoabsorption coefficient, which is proportional to the absorption cross-section. The

• substrate since both materials absorb at the laser wavelength. For the NPs, this absorption results in the increase of their temperature and induces desorption of Co and Pt atoms. The absorption cross section of the UV radiation varies as d3, where d is the diameter of the NPs [13][27]. Desorption phenomena
