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). magnified image
