X Ray Spectroscopy
This is a comprehensive note on X-ray spectroscopy techniques, aimed at detailing their applications in different fields, with an emphasis on the special applications in nanoparticles and molecular mechanisms. It begins with the introduction of XRF processes and techniques followed by high-resolution X-ray spectroscopy using compound semiconductor detectors and digital pulse processing systems. It also includes analytic applications of X-ray techniques, including dispersive X-ray spectroscopy as well as quantification in X-ray fluorescence spectrometry. In addition, it approaches specialized uses such as time-resolved X-ray absorption spectroscopy in the study of metalloproteins and the application of soft X-rays in astrochemistry. The note concludes discussing nanoscale chemical analysis that highlights energy dispersive X-ray spectroscopy (EDX) and transmission electron microscopy (TEM) with relevance to the characterization of interfaces and materials on the nanoscale.
