摘要： 在超声分子束中,使用双光子共振电离光谱技术和飞行时间质谱技术研究了复合物邻二甲苯…Ar,N2,NH3(ND3).通过理论计算及同位素光谱效应,合理地归属了这些复合物的光谱,并由此获得这些复合物分子间各种模式的振动频率.

Abstract: Resonant two-photon ionization spectra of van der Waals complexes C6H4(CH3)2:Ar, N2, NH3were reported by using one-color resonant ionization technique, together with time-of-flight mass spectrometry, in supersonic molecular beam. All observed bands were rationally assigned by calculated levels, isotope effect, and spectral analysis. According to the spectra assignment, the frequencies of van der waals vibrations for these complexes were obtained.

Key words: Resonant photo-ionization spectra, van der Waals complex, Time-of-flight mass spectrometry
