If the package consists of direct executable files without an installer, simply launch the XPSPeak41.exe file directly from the extracted folder. Step 3: Configuring Windows Compatibility (If Needed) If the program fails to launch or crashes on Windows 10/11:
Select the appropriate background type (Shirley is recommended for most routine polymer and oxide analyses) and click . Peak Addition and Constraint Setting I'll search for relevant information
这通常有两个原因：一是背底扣除不准确，可以尝试将Backgrond类型切换为“Shirley+Linear”或“Tougaard”再试试；二是初始峰的设置不合理，多加一个峰或少加一个峰，或通过“Constraints”为参数设置合理的边界范围。
XPSPEAK 4.1 is a classic, freeware Windows application designed for the processing and curve-fitting of XPS data. Developed originally by Professor Raymond Kwok, the software allows users to decompose broad, overlapping XPS spectral envelopes into individual chemical components using Gaussian-Lorentzian sum or product functions. Key capabilities of the software include:
