Cover Picture: Direct Observation of Charge-Transfer Reactions in Nanoscopic Test Tubes: Self-Ionization in HNO3 Clusters (ChemPhysChem 3/2003)

4_03/2003The cover picture shows schematically the release of charge carriers from a molecular cluster via cluster fragmentation caused by a surface collision. In the incoming cluster, which is neutral as a whole, a charge-transfer reaction has previously generated equal numbers of positive- and negative-charge carriers. The subsequent fragmentation now breaks the cluster apart and forms mass-spectrometrically observable free charge carriers, represented here by the blue and the red sphere. Thus, surface collisions of large molecular clusters allow the direct observation of bulk-phase charge-transfer processes by mass spectrometry. Find out more in the communication by Gebhardt et al. on pp. 308–312.
