Abstract:We present measurements of the electronic absorption spectrum of He-tagged buckminsterfullerene anions, C60. Using a technique that allows for the efficient tagging of complex molecular anions with He, we achieve atomically resolved action spectra that provide an accurate determination of the gas-phase absorption spectrum in the near-infrared regime. In total we identify 27 absorption bands between 895 and 1057 nm.
