| 摘 要： | 利用双光子共振电离光谱和飞行时间质谱技术在超声分子束中观察到C6H5CH3…Ar的振动光谱.借助同位素光谱效应、内转动能级和分子间振动能级的理论计算,合理地归属了涉及CH3转动和Ar原子振动的光谱,并由此获得复合物分子间各种模式的振动频率.

| Abstract: | A combined experimental and theoretical studies of resonant ionization spectra for van der Waals complexes C 6H 5CH 3...Ar and C 6D 5CD 3...Ar are reported. By using resonant ionization spectrometry, together with time-of-flight mass spectrometry, in supersonic molecular beam, the internal rotation for CH 3 and intermolecular vibration for atom Ar in the complexes are exhibited , all observed bands are rationally assigned by isotope effect and calculated at the internal rotational levels and external vibrational levels, and three modes frequencies of van der waals vibrations for complex C 6H 5CH 3...Ar are obtained. |
