The applications of kinetics calculations to determine the size distribution of C n clusters formed from the vaprized material of graphite requires aknowlledge of the initial composition of the carbon vapour. By a 13 C iisotope tracer experiment it is shown that a considerable part of the C n molecules in the case of n⩾3 evaporate directly as polyatomic fragments of the crystal structure of graphite, while the other, probably the greater part, is formed in the vapour. A more quantitative evalution of the experimental data is to be attempted later.
