Study of He/Ne+Ar, Kr, N2, H2, D2 Chemi-Ionization Reactions by Electron Velocity-Map Imaging

Andreas Osterwalder, Sean Dennis Steven Gordon, Junwen Zou, Silvia Tanteri

The chemi-ionization of Ar, Kr, N2, H2, and D2 by Ne(3P2) and of Ar, Kr, and N2 by He(3S1) was studied by electron velocity map imaging (e-VMI) in a crossed molecular beam experiment. A curved magnetic hexapole was used to state-select the metastable speci ...

Optical properties and photochemical production of hydroxyl radical and singlet oxygen after ozonation of dissolved organic matter

Urs von Gunten, Frank Jonathan Leresche

This study focuses on the effects of ozonation on the optical and photochemical properties of dissolved organic matter (DOM). Upon ozonation, a decrease in light absorption properties of DOM was observed concomitantly with a large increase in singlet oxyge ...

Synthesis of Benzo[a]carbazoles through Visible Light-Induced Cycloaromatization

Qian Wang, Jieping Zhu, Bo Yao

We report herein a synthesis of 5,6-diarylbenzo[a]carbazoles by a sequence of 6 pi-electrocyclization followed by beta-elimination. The highly functionalized 2,3-disubstituted indoles used for this cycloaromatization process are prepared by Pd-catalyzed cy ...
