摘要
We report a joint photoelectron spectroscopic and theoretical study on the molecular anion, quinoline(-). Analysis of the vibrationally resolved photoelectron spectrum found the adiabatic electron affinity, EA(a)(C9H7N), to be 0.16 +/- 0.05eV. These findings were supported by density functional theory calculations. Our experimental and computational results demonstrate the unusual electrophilicity for a polycyclic aromatic heterocycle.
