| 摘 要： | 利用三阶微商吸收光谱观测到了紫外一可见区Ｃ６０更为丰富捐收跃迁结构，基于 伦兹线型假设，实验上拟合确定了相应迁能量和寿命加宽参数，并对跃迁结构进行了初步指认，给出了部分振动模的频率。与常规吸收光谱比较，表明了三阶微商光谱是分析Ｃ６０等团簇光物理特性的有效手段。

| Abstract: | More detailed absorption transitions of C 60 in the UV/visible region are observed from the third order derivative absorption spectra. The spectra are fitted with Lorentzian line shapes, and the transition energies and broadening parameters are determined. The assignment of the transtions in visible region is discussed,and some vibronic modes are given. In comparison with normal absorption spectrum technique, the third order derivative absorption technique has been shown an effective method for the study of optical and physical characteristics of atom clusters such as C 60 . |
