How much quantitative information may be expected from programmed desorption experiments

摘要: Abstract We have integrated numerically the differential equation for temperature-programmed first order thermal desorption: dθ/dt = − θνexp( - E/kT), where θ is coverage. By changing dependence of ν and E on T we can simulate diverse effects resulting spectra predict which ones could be distinguished not. The results show that considerably less quantitative information reliably obtained than it generally supposed “refined” analysis may lead to unrealistic conclusions. propose good desorption experiments light rare gases at low temperatures compared more with existing one-phonon theories.
