| Abstract: | The synthesis of fullerenes was carried out using dc arc discharge technique. The separation and identification of higher fullerene C84 was done by high performance liquid chromatography (HPLC). The raw soot collected from the high temperature region was dissolved in toluene and then toluene-extracted soot dissolved in n-hexane and kept in laboratory environment for more than one month. The peaks of C60 and C70 along with C84 were observed. The existence of C84 was confirmed by using linear regression between capacity factor log k′] and the carbon number. |
