  Magnetism of fullerene C60 was studied by three methods of the density
functional theory (DFT) calculation, laboratory experiment and astronomical
observation. DFT revealed that the most stable spin state was non-magnetic one
of Sz=0/2. This is contrary to our recent study on void induced graphene
molecules of C23 and C53 to be magnetic one of Sz=2/2. Two graphene molecules
combined model suggested that two up-spin at every carbon pentagon ring may
cancel each other to bring Sz=0/2. Similar cancelation may occur on C60.
Molecular vibrational infrared spectrum of C60 show four major bands, which
coincide with gas-phase laboratory experiment, also with astronomically
observed one of carbon rich planetary nebula Tc1 and Lin49. However, there
remain many unidentified bands on astronomical one. We supposed multiple voids
on graphene sheet, which may create both C60 and complex graphene molecules. It
was revealed that spectrum of two voids induced graphene molecule coincident
well with major astronomical bands. Simple sum of C60 and graphene molecules
could successfully reproduce astronomical bands in detail.
