Because XPSPEAK 4.1 is a legacy program, it does not have a single, centralized modern repository. However, it is safely hosted by various academic institutions and research gateways. Step 1: Downloading the Software
The interface is focused. It doesn't have the steep learning curve of more "bloated" professional suites.

XPSPEAK 41 (often written as XPSPEAK 4.1) is a Windows-based software program designed for the processing and peak fitting of XPS spectra. Developed by Professor Raymond Kwok, the software allows users to decompose complex, overlapping photoelectron peaks into individual chemical components. This process is essential for determining the chemical bonding states, oxidation states, and elemental composition of a sample's surface. Key Features
: New users often find the interface locked; the software requires you to add and "accept" a background before any peaks can be added or fitted. Adding and Fitting Peaks Click on Add Peak
XPSPEAK 4.1 is a widely used freeware application designed for visualizing and fitting X-ray photoelectron spectroscopy (XPS)
Open a sample file (e.g., Cu2p_bg from the folder) and attempt to fit the first peak to ensure everything is working correctly.
