The reason these line shapes are appropriate for measuring peak intensities is that both functions, when integrated from minus infinity to plus infinity are finite. Indeed, for all normal uses of the Gaussian-Lorentzian line shapes, the intensity as measured by fitting these functions to the data...
• Fix the %GL in the later peak fitting process when the same instrument settings were used. This version also includes the setting of the upper and lower bounds for each parameter. 2. 3. 4. Peak Parameters This program uses the following asymmetric Gaussian-Lorentzian sum function 6.9 ...
The spectra were decomposed with the least squares fitting routine provided by the manufacturer with a Gaussian/Lorentzian ratio of 85/15 and after subtraction of a calculated baseline. View chapter Book series 1998, Studies in Surface Science and CatalysisH.M. Wiame, ... P. Grange Chapter ...

XPS Peak Fitting Program for WIN95/98 XPSPEAK Version 4.1 Program Installation XPS Peak is freeware. Please ask RCSMS lab staff for a copy of the zipped 3.3MB file, if you would like your own copy Unzip the XPSPEA4.ZIP file and run Setup.exe in Win 95 or Win 98. ...
Calculation of the asymmetrical function using the Gaussian-Lorentzian product function was too difficult to implement. The software of some instruments uses the sum function, while others use the product function, so both functions are available in XPSPEAK. See Peak Function, (Page 12) for ...
However, quantitative analysis based on Gaussian/Lorentzian (G/L) peak fitting suffers from the challenges of reproducibility and effectiveness. In this study, the Ni 2+ and Ni 3+ standard samples and a series of NMC samples with different Ni doping levels were synthesized. The Ni 2+ /Ni 3...
