Influence of the emission site on the photoelectron circular dichroism in trifluoromethyloxirane

Abstract

The photoelectron circular dichroism is strongly influenced by the origin where the electron is set free.

Trends in angle-resolved molecular photoelectron spectroscopy

“…344 Exploring 3D MFPADs for K-shell ionization of more complex molecules using 3D momentum spectroscopy of both electron and ion fragments is pursued: recent applications address in particular PECD for space-fixed chiral molecules. 323,345,346 We illustrate below two recent results addressing MF photoionization time delays, and PAD analysis for core-shell ionization of space fixed chiral molecules.…”

“…A similar analysis in the trifluoromethyloxirane has been further conducted for four initial ionization bands, the two unresolved carbon atoms of the ring, the CF 3 carbon, and the three unresolved fluorine atoms, in addition to oxygen. 346 The PECD of space fixed oriented chiral molecules may then stand as a sensitive structural and analytical technique for the enantiomeric excess determination, at the cost however of a more complex experiment. Rationalizing the influence of spatial alignment of molecules photoionized by CPL is as well relevant for the interpretation of PECD studies relying on REMPI which induces partial alignment of the molecule.…”
