| Abstract: | Recent studios of the molecule adsorption on metal surfaces by using photoacoustic spectroscopy have been reported. The superior chatacteristics of PAS have been demonstrated by the following results: the vibrational spectra for studying physisorption under high exposure pressure; the adsorption mechanism of multilayer growth measured by phase discriminated spectra and the precursor adsorption kinetics analyzed by the adsorption isotherm. |
