摘要：
Two methods of quantitative analyses of the fullerenes C-60 and C-70 are described. Quantitative Infrared Spectroscopy permits the determination of the concentrations of pure and mixed compositions of C-60 and C-70 in carbondisulfide solutions. Alternatively, the ratio of C-60/C-70 is analyzed by evaluating the lattice parameters of a solid solution of the fullerene species and cyclohexane according to Vegard's Law. Both methods show high accuracy and are suited for calibration of mass spectrometric analyses of fullerene samples.
