Fig. 1: Time series absorbance spectra of C60 under UV excitation of 3.74 mW/cm2.
From: Single-photon oxidation of C60 by self-sensitized singlet oxygen

a In C6H14; b in CCl4. The inset of (b) shows photos of C60 solutions, unexposed and after 8 min of UV exposure. c The spectrum of the excitation source, UVP XX-15 UV lamp.
