Single and Multiphoton Ionization of Chiral Molecules

We will show how linear, planar and chiral molecules react to circular polarizied light. We will discuss single photon ionizations and ionization and fragmentation in a strong laser field measured with a COLTRIMS Reaction Microscope. We will discuss the following findings: \begin{itemize} \item Circular polarized light leads to chiral electron emission pattern even for achiral species. \item Chirality can be enantioselectively induced in a planar molecules by a femtosecond laser pulse. \item Photoelectron and photoion circular dichroism is enhanced by an order of magnitude whenever at least one momentum vector of one particle is measured. \end{itemize}
