X-ray Photoelectron Spectra of Organic Compounds

X-ray photoelectron spectra of iron-sulphur proteins.

The X-ray photoelectron spectra of the 2p, 3s and 3p levels of iron in oxidized Clostridium pasteurianum ferredoxin indicate that the eight iron atoms in the molecule are indistinguishable. Their magnetic state is indicated both by core polarization splitting of the 3s electrons, and by "shake-up' satellites on the 2p lines. Similar satellites are observed in the 2p lines of reduced Chromatium ...

Photoelectron X-ray Microscopy

The soft-X ray range, between 1-10 nm wavelength, is highly interesting for X-ray microscopy. Taking advantage of it requires, however, to operate a high resolution instrument at a variable wavelength. We describe here an image converter X-ray microscope which is based on secondary pharoemission. This instrument is now developped at the Institut dlOptique (Orsay); it will be installed near ACO ...

Photoelectron Spectra and Bonding in Phosphorus Compounds'

The results of (low energy) photoelectron spectroscopy render possible a better appreciation of bonding in molecules. The application of the new experimental method is demonstrated utilizing representative phosphorus compounds, and the close symbiosis delineated with molecular orbital models. Among the topics discussed are: the element P4, phosphine PH3 and derivatives, phosphorus substituent e...

THEORY OF X-RAY EMISSION SPECTRA IN Ce COMPOUNDS

X-ray emission spectra (XES) corresponding to the Ce 5p + 3d transition in insulating Ce compounds are studied theoretically with the impurity Anderson model. It is shown that the XES reflects the dynamical relaxation through the hybridization between 4f and valence band states, as well as the lifetime of 3d core hole.
