While no longer actively updated, this software is widely used in academic research for deconvoluting and fitting XP spectra. It is particularly effective for users who need a lightweight, no-cost alternative to expensive commercial suites like CasaXPS.
Fix certain parameters to maintain physical consistency (e.g., keeping a 2:3 ratio for p-orbitals).
) error until the synthetic envelope perfectly matches your raw experimental data points. Common Alternatives to XPSPEAK
XPSPEAK 4.1 was natively architected for 32-bit platforms, meaning Windows 64-bit systems require a specific directory extraction routine to function without permission runtime errors: Downloading the XPSPEAK41 software

XPSpeak (specifically XPSpeak 4.1) is a legacy Windows-based software designed for peak fitting and processing of XPS spectra. Developed by Professor Raymond Kwok, it provides a user-friendly interface to decompose complex, overlapping photoelectron envelopes into individual chemical state components. Key Features
: Quantify peak areas, positions, and widths for chemical state identification. Key Features of XPSPeak 4.1
Once you have successfully performed the XPSpeak download and installation, here is a quick start guide to analyzing your data.
Once installed, XPSPeak provides a streamlined workflow for XPS data analysis: 1. Data Import While no longer actively updated, this software is
Ensure the data structure consists strictly of two columns: and Intensity (Counts) .
If you are looking to download XPSPEAK and want to understand how to maximize its utility for your research, this comprehensive guide will walk you through its core features, installation steps, and a practical peak-fitting workflow. Key Features of XPSPEAK
XPSPEAK 4.1 does not utilize a modern, automated wizard installer. Instead, it distributes as a "cabinet" compressed file ( .cab ) or a .zip archive that must be unpacked manually to prevent runtime errors:
It offers specialized parameters to fit asymmetric peaks, which are commonly observed in metallic systems (e.g., pure transition metals). ) error until the synthetic envelope perfectly matches
With powerhouse programs like CasaXPS or Avantage on the market, why do people still look for an XPSPEAK download?
Once your software is up and running, follow this foundational workflow to process your raw data. 1. Preparing and Importing Data
Click on to let the software's algorithm automatically adjust the unconstrained parameters to minimize the Chi-squared ( χ2chi squared
Click on . A new window will pop up allowing you to customize Component 1 (e.g., in a Carbon 1s spectrum). Choose the Peak Type ( orbitals if dealing with spin-orbit doublets).
