C_(42)〈Al〉C_(32)〈Si〉等混合物吸收光谱特性

CHARACTERISTICS OF THE ABSORPTION SPECTRA OF THE MIXTURES OF C 42 〈Al〉,C 32 〈Si〉 AND SO ON

用电弧放电［１］、Ｈｅ气对流的方法制备出了含Ｃ４２〈Ａｌ〉、Ｃ３２〈Ｓｉ〉、Ｃ２８〈Ｆｅ〉和Ｃ３０〈Ｃａ〉的混合物。对该混合物作了吸收光谱测量，并与Ｃ６０等全碳分子的吸收光谱作了比较，结果表明，Ａｌ、Ｓｉ、Ｃａ和Ｆｅ原子嵌入Ｃ４２等全碳分子后，并没改变吸收峰位，而只是改变了分子的π→π＊跃迁和ｎ→π＊跃迁几率。

The mixtures containing C 42 〈Al〉、C 32 〈Si〉、C 30 〈Ca〉 and C 28 〈Fe〉 are produced by means of arc discharge and He gas convection.The spectra are measured and compared with the absorption spectra of all carbon molecules.The result shows that after imbeded in all carbon molecules,the Al、Si、Ca and Fe atoms do not change the positions of the absorption peak of original molecules,but only change the probability of π→π  transition and n→π  transition of these molecules.
