摘 要: 由复合物C6H5CH3…N2共振双光子电离光谱获得了复合物分子间范德华振动模式和N2的内转动的大量信息.通过对比同位素分子C6D5CD3…N2的光谱,我们合理地归属了所观察到的C6H5CH3…N2复合物的所有谱线.由光解离碎片的机理分析,推得复合物C6H5CH3…N2的激发态和基态的键能大约是494和474cm-1,与理论计算值非常接近. The resonant two-photons ionizatio n technique is employed to study jet-cooled van der Waals(vdW)complex C 6 H 5 CH 3 ...N 2 through the S 1 ←S 0 transition.By Comparing the spectr a of isotopic complex C 6 D 5 CD 3 ...N 2 ,we have tentatively assigned all th e observed spectral features to the c omplex C 6 H 5 CH 3 ...N 2 .The rich information about the complex i ntermolecular vdW viberational mod es and internal rotation of N 2 are ob-tained by the spectra.The binding en ergies for the complex C 6 H 5 CH 3 ...N 2 in the excited electronic state and i n the ground electronic state are abou t 494cm -1 and 474cm -1 ,those are very close to the calculated values.
