Cover Picture: Excited-State Relaxation of Protonated Adenine (ChemPhysChem 5/2007)
The cover picture shows the potential energy scheme of protonated adenine. The adenine molecule in front is in the ground-state equilibrium geometry whereas the molecule in the back shows the nonplanar structure after absorption of an UV photon. In their Article on page 751 Nolting et al. investigate the excited state dynamics of protonated adenine by femtosecond pump–probe transient mass spectrometry in the gas phase.
