Circular dichroism in core level photoemission from an adsorbed chiral molecule.
نویسندگان
چکیده
The results of experimental measurements and theoretical simulations of circular dichroism in the angular dependence (CDAD) of photoemission from atomic core levels of each of the enantiomers of a chiral molecule, alanine, adsorbed on Cu(110) are presented. Measurements in, and out of, substrate mirror planes distinguish CDAD due to the chirality of the sample and the experimental geometry. The effect due to sample chirality is relatively weak, so such measurements may not provide a routine spectral fingerprint of adsorbate chirality.

Atom-specific identification of adsorbed chiral molecules by photoemission.
The study of chiral adsorbed molecules is important for an analysis of enantioselectivity in heterogeneous catalysis. Here we show that such molecules can be identified through circular dichroism in core-level photoemission arising from the chiral carbon atoms in stereoisomers of 2,3-butanediol molecules adsorbed on Si(100), using circularly polarized x rays. The asymmetry in the carbon 1s inte...
متن کاملCan circular dichroism in core-level photoemission provide a spectral fingerprint of adsorbed chiral molecules?
The results of experimental measurements and theoretical simulations of circular dichroism in the angular distribution (CDAD) of photoemission from atomic core levels of each of the enantiomers of a chiral molecule, alanine, adsorbed on Cu(1 1 0) are presented. Measurements in, and out of, substrate mirror planes allow one to distinguish the CDAD due to the chirality of the sample from that due...
متن کاملChirality transfer from gold nanocluster to adsorbate evidenced by vibrational circular dichroism
The transfer of chirality from one set of molecules to another is fundamental for applications in chiral technology and has likely played a crucial role for establishing homochirality on earth. Here we show that an intrinsically chiral gold cluster can transfer its handedness to an achiral molecule adsorbed on its surface. Solutions of chiral Au38(2-PET)24 (2-PET=2-phenylethylthiolate) cluster ...
متن کاملPlasmonic circular dichroism in side-by-side oligomers of gold nanorods: the influence of chiral molecule location and interparticle distance.
Chiral metal nanostructures, which exhibit plasmonic circular dichroism (PCD), have great potential for the development of chiral sensors and devices. Previously, we developed a method for fabricating chiral gold-nanorod oligomers: the nanorods are linked by achiral molecules, while chiral molecules (e.g.l- or d-cysteine) on the Au surface exert a directional twisting force on the oligomers and...
متن کاملDepth profile high - energy spectroscopic study of Mn - doped GaN prepared by thermal diffusion
We have performed an in-situ depth profile study of Mn-doped GaN prepared by a low temperature thermal diffusion method using photoemission and x-ray absorption spectroscopy. It was revealed from the core-level pho-toemission measurements that Mn ions are diffused into a deep (∼ 70Å) region of the GaN substrates and that the line shapes of Mn 3d partial density of states obtained by resonant ph...
