摘要
报道了C_(60)球烯的制备分离过程,并对所获得的纯C_(60)粉末样品和膜样品进行了^(13)C核磁共振,傅里叶红外以及Raman谱研究.结果表明:C_(60)样品在红外有4个吸收峰,分别位于528、578、1182、1429cm^(-1)处;在Raman谱中观察到3个峰,分别位于273、469、1465cm(-1)处;^(13)C核磁共振谱则表明在143.2 ppm化学位移处有一单峰,这些都与理论计算值相符,很好地证实了C_(60)的全碳和高度对称的球形结构.
The preparation and separation of fullerene C_(60) by contact arc method is reported . The studies of
(13)~C NMR,FTIR and Raman spestra have been made for pure C_(60) solid power and film samples . The four lines
(528,578,1182,1429 cm^(-1))in the FTIR spectrum,three lines (273,469, 1465 cm(-1))in the Raman Spectrum,
and one line (143. 2 ppm) in the ^(13)C NMR Spectrum for C_(60) have been observed . The results were in good a-
greement with theoretical predictions and strongly supporting the all-carbon and icosahedral point group sym-
metry molecule.
