Multiwfn 3.8 Download ^hot^ Info
A huge collection of examples is available on Sobereva's blog.
Multiwfn 3.8 was officially released on January 7, 2026. Prior to the official release, development versions were frequently updated on the official website, with updates sometimes occurring multiple times per day.
Multiwfn, developed primarily by Dr. Tian Lu, is an indispensable tool in computational chemistry for analyzing wavefunctions and electron densities. Known for its powerful capabilities in real-space analysis, topological analysis (AIM, ELF, LOL), and the calculation of various spectroscopic properties, the program is released as freeware for academic users. For researchers and students seeking version 3.8, understanding where and how to download the software properly is essential to ensure file integrity and access to the full suite of features.
is an interactive, multifunctional wavefunction analyzer. It parses output files from major quantum chemistry packages—such as Gaussian, ORCA, Q-Chem, and multi-purpose formats like .wfn , .wfx , .fchk , and .molden —to calculate a massive array of molecular properties. Key core capabilities include: multiwfn 3.8 download
On this page, navigate to the "Download" section. Here, you will find a comprehensive list of available files. The developer has implemented a new version naming convention starting in 2026. While "3.8" is the last version under the old system, newer updates are now named by their release date (e.g., Multiwfn_2026.1.12 ). It is strongly recommended to download the most recent dated version for the latest features and fixes.
Multiwfn can be run non-interactively using command-line arguments and input scripts. This is particularly useful for processing large numbers of files. See Sections 5.2 and 5.3 of the manual for detailed instructions.
: Version 3.8 natively supports deep electronic analysis of high-level wavefunctions, including CCSD(T), CCSDT, and MP5 . This integrates via JSON files generated by ORCA 6.1 . A huge collection of examples is available on
Download the dedicated version for Mac users. Ensure you choose the binary matching your hardware architecture (Intel vs. Apple Silicon via Rosetta/Native compilation if available). Step 3: Extract the Package
: Adds strict constraints to the CHELPG and Merz-Kollman (MK) electrostatic charge fitting interfaces, forcing the resulting atomic charges to perfectly reproduce the system's exact calculated electric dipole moment.
Excellent tools for NCI (Non-Covalent Interactions) and IGM (Independent Gradient Model) plots. Population Analysis: Includes Hirshfeld, Becke, VDD, and many more. Orbitals & Density: Multiwfn, developed primarily by Dr
