X-ray absorption spectroscopy (XAS), often referred to as X-ray absorption fine structure (XAFS) spectroscopy, is a powerful technique available for determining the local coordination site structure and electronic properties of specific atoms in molecules. XAS can be performed on molecules in the ...

1. A study on purification process of single wall carbon nanotubes(SWCNTs) synthesized by CVD method was performed using X-ray absorption spectroscopy (XAS) and photoelectron spectroscopy. 用X射线吸收谱(XAS)和光电子能谱(PES)对化学气相沉积(CVD)方法制备的单壁碳纳米管纯化过程进行了研究。
X-ray Absorption Spectroscopy (XAS) When the x-rays hit a sample, the oscillating electric field of the electromagnetic radiation interacts with the electrons bound in an atom. Either the radiation will be scattered by these electrons, or absorbed and excite the electrons. x A narrow parallel ...
XAS(X-ray absorption spectroscopy) is known as an X-ray analytical technique to determine the local structure of a desired atom under any sample condition such as in crystal, amorphous, and solution. From: Advances in Quantum Chemistry, 1998 ...
This fact is not astonishing, since common methods of physical chemistry, like molecular weight determination, IR- and NMR-spectroscopy, conductivity measurements etc. do not provide direct information about the precursor structure. X-ray absorption spectroscopy, however, is a powerful method for ...
