The isomer formation of three isomers of C[sub 78] fullerene is discussed on the basis of experimental evidence revealed by pressure-controlled fullerene production. Theoretically predicted most stable isomer, C[sub 2v][prime]-C[sub 78] has been found to be very sensitive to the graphite burning condition. The fraction of C[sub 2v][prime] isomer dramatically changes from zero to 50% by changing the foreign gas pressure. The present findings strongly suggest that an isomerization within the C[sub 78] carbon network such as a pyracylene rearrangement type transformation unlikely takes place. 21 refs., 3 figs.
