摘要
报道在超真空系统中利用激光光声振动谱研究表面吸附的实验结果。通过振动谱在高背景气压下的可逆物理吸附及位相甄别法研究NH_3分子双层吸附生长机理等实例,展示出激光光声谱是一种较理想的表面吸附研究手段。
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.
