Spectroscopy detects elements with atomic number of 3 and above only.
Neumark, Examination of the Br + HI, and F + HI hydrogen abstraction reactions by photoelectron
spectroscopy of BrHI-, ClHI-, and FHI-, J.
In this expression, E is the photoelectron
kinetic energy, [theta] is the electron ejection angle relative to the laser polarization direction, and t is the pump--probe time delay.
Cuprous and cupric oxides can be distinguished in the photoelectron
Cu 2p spectra, since cupric compounds show two strong shake-up peaks located approximately 10eV above the principal Cu 2p3/2 peak.
It is important to note that these contaminants are not observed with other surface techniques such as scanning electron microscopy, where chemistry is measured at a micrometer scale two or three orders of magnitude deeper into the surface than what is probed by X-ray photoelectron
Factoring in both the positional dependence of the effciency and the beta-decay spectrum of the electrons, we obtain a detection effciency of (48 [+ or -] 6) % when photomultiplier tube (PMT) threshold levels are set to three or more photoelectrons
Some may question the choice of including a chapter on photoelectron
spectroscopy, but more may note that one of the longest chapters is the last one, on laser spectroscopy.
The isotherm in the chemisorption region for this study was of the Langmuir type, according to experimental data fitting and as observed by X-ray photoelectron
spectroscopy (XPS) analyses.
Attenuated Total Reflection Fourier Transform Infrared spectroscopy, X-ray Photoelectron
spectroscopy, protein absorption and Fluorescence imaging were used.
Non-traditional techniques, including Auger electron spectroscopy, X-ray photoelectron
spectroscopy, Mossbauer spectroscopy, and cathodoluminescence microscopy, are also beneficial in determining mineralogical interactions of processed materials.
