ESR spectra of fullerene nano-whiskers (FNW) are investigated to elucidate their electronic properties and the influence of oxygen absorption. A singlet ESR spectrum appears together with temperature independent Pauli-para type behavior in the area intensity (which indicates the magnetic susceptibility (χESR)) in vacuum. Motional narrowing of the absorption width is observed in vacuum due to fast molecule motion. Absorption of oxygen eliminates Pauli-para behavior and motional narrowing. Furthermore, creation of localized spins is observed and χESR shows no Pauli-para contribution after absorption. A kind of metal insulator transition due to gas absorption is therefore observed by ESR in the system of C60 FNW.
