Inside Cover: Absorption Spectra of 4-Nitrophenolate Ions Measured in Vacuo and in Solution (ChemPhysChem 8/2009)
The inside cover picture shows gas-phase absorption spectra of four p-nitrophenolates. The ions cover the entire visible spectrum when isolated in vacuo and are located within a narrower region in solution. On p. 1207 A. Rubio, M. Brøndsted Nielsen, S. Brøndsted Nielsen et al. use the gas-phase absorption maxima to benchmark excitation energy calculations (blue lines).
