520 ▼a The electronic structure of molecular systems is responsible for a wide range of phenomena including fluorescence, phosphorescence, and many effects in semiconductors. One of the most remarkable is singlet fission, in which a singlet excitation
520 ▼a This work details the construction of an instrument capable of performing anion photoelectron spectroscopy, one of the few techniques with access to singlet and triplet states on equal footing. The spectrometer is a new design, capable of provid
520 ▼a Presented here is the first anion photoelectron study of the fluoranthene molecule, and the highest-resolution study to date of the anthracene molecule. Results show the clear presence of vibronic coupling in the singlet and triplet manifolds of
520 ▼a The aromatic oxide radicals contain an oxygen atom bonded to the aromatic ring, which imparts a significant dipole moment to the neutral system. This dipole moment is strong enough to weakly bind an electron and produces photoelectron spectra wh
