The molecular structure of C₇₀ has been studied between 20 and 300 K using high-Q pulsed powder neutron diffraction of solid C₇₀. The intra- and inter-molecular pair correlation functions were decoupled, allowing accurate determination of the intramolecular structure of C₇₀. The CC bond lengths range between ≈ 1.38 and 1.48 Å with no evidence of pinching in the equatorial region. There is essentially no change in the intermolecular structure on cooling, in contrast to the severe changes in the intermolecular pair correlation function that accompany orientational ordering.

C ₇₀富勒烯的分子结构

使用固体C _70的高Q脉冲粉末中子衍射研究了C ₇₀的分子结构，范围为20至300K 。分子内和分子间相关函数解耦，可以准确确定C ₇₀的分子内结构。CC键的长度范围在≈1.38至1.48Å之间，没有证据表明在赤道区域会发生收缩。冷却时，分子间结构基本上没有变化，这与伴随取向排列的分子间对相关函数的剧烈变化相反。
