BACKGROUND: Ampelozizyphus amazonicus Ducke, a plant that is widely used by the population of the Amazonian region to prevent and treat malaria, was investigated in this work, which describes, for the first time, the antiplasmodial activity of its extracts...

Synchrotron-based valence shell photoionization of CH radical.

The Journal of chemical physics

Gans B, Holzmeier F, Krüger J, Falvo C, Röder A, Lopes A, Garcia GA, Fittschen C, Loison JC, Alcaraz C.
PMID: 27250306
J Chem Phys. 2016 May 28;144(20):204307. doi: 10.1063/1.4950880.

We report the first experimental observations of X(+) (1)Σ(+)←X (2)Π and a(+) (3)Π←X (2)Π single-photon ionization transitions of the CH radical performed on the DESIRS beamline at the SOLEIL synchrotron facility. The radical was produced by successive hydrogen-atom abstractions...
