the isotopic abundance, m
is the number of 13C per fullerene, and pJC ) is the probability a fullerene C„(. has m C atoms. Although the table would normally be used for small concentrations of 13C in C„c, the same probabilities as given in the table apply to 1.108% 12C in 98.892% "C, or to 5% ,2C in 95% 13C, or to 10% 12C in 90% 13C.
