Pharmaceutical Compounds Studied Using NEXAFS

AIP Conference Proceedings, 2007
Total Electron Yield (TEY) oxygen K-edge NEXAFS detects the presence of strongly adsorbed water molecules on poloxamer-coated pharmaceutical actives, which provides a useful spectroscopic indicator for bioavailability. The results are supported by complementary XPS measurements. Carbon K-edge spectra obtained in a high-pressure NEXAFS cell were used in

NEXAFS spectroscopy of conjugated polymers

European Polymer Journal, 2016
Abstract This feature article provides a general introduction to Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy of conjugated polymers as well as a perspective on the information that NEXAFS spectroscopy is able to provide. While conjugated polymers are of interest for a range of applications including organic light-emitting diodes ...

NEXAFS and XPS studies of nitrosyl chloride

Physical Chemistry Chemical Physics, 2015
The electronic structure of nitrosyl chloride (ClNO) has been investigated in the gas phase by X-ray Photoelectron (XPS) and Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy at the Cl 2p, Cl 2s, N 1s and O 1s edges in a combined experimental and theoretical study.

Analytical theory of NEXAFS from diatomic molecules

Physical Review B, 1996
Analytical expressions are derived for both the ${\mathrm{\ensuremath{\pi}}}^{\mathrm{*}}$ and ${\mathrm{\ensuremath{\sigma}}}^{\mathrm{*}}$ resonances in near-edge x-ray-absorption fine-structure (NEXAFS) spectra from diatomic molecules. A simple criterion is formulated for extracting structural parameters (e.g., the bond lengths) of such molecules ...

NEXAFS spectromicroscopy of suspended carbon nanohorns

Chemical Physics Letters, 2013
Abstract We demonstrate that near-edge X-ray-absorption fine-structure spectroscopy combined with full-field transmission X-ray microscopy can be used to study the electronic structure of suspended carbon nanohorns. Based on reports of electronic structure calculations additional spectral features observed in the π region of the NEXAFS spectrum ...

The NEXAFS of biological calcium phosphates

Review of Scientific Instruments, 1995
The absorption cross section of a number of calcium salts has been assessed at the calcium L edge by measuring the total electron yield (TEY) at the NSLS U13UA beamline. TEY was used because of distortions introduced by instrumentation when using a transmission signal. The effect of these distortions has been evaluated and is presented.

NEXAFS Spectra of Polymer‐nanocarbon Composites

Fullerenes, Nanotubes and Carbon Nanostructures, 2008
The near edge X‐ray absorption fine structure (NEXAFS) spectra of polymethylmetacrylate (PMMA)‐fullerene (Fu) C60 and PMMA‐multiwall nanotubes (MWNT) composites treated at different temperatures are compared to the thermal desorption (TD) mass‐spectrometric (MS) spectra.

Recent progress in EXAFS/NEXAFS spectroscopy

Journal of Electron Spectroscopy and Related Phenomena, 2014
Abstract We briefly review the basic theory and recent applications in the X-ray absorption fine structure (XAFS) spectroscopy. First we discuss a dressed one-electron XAFS formula starting from many-body scattering theory, where important many-body effects, intrinsic and extrinsic losses, and optical potential are naturally introduced. Next multiple
