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 C_ (60) polyalkenes were reported, and ~ (13) C nuclear magnetic resonance, Fourier transform infrared and Raman spectra of pure C_ (60) powder samples and membrane samples were studied.The results show that: The C_ (60) samples have four absorption peaks at infrared at 528, 578, 1182 and 1429 cm -1, respectively. There are three peaks in Raman spectrum at 273, 469 and 1465 cm -1, The ~ (13) C nuclear magnetic resonance spectrum showed a single peak at 143.2 ppm chemical shifts, all in agreement with the theoretical calculations, which well confirmed the C_ (60) carbon and the highly symmetrical spherical structure.
