In the world of computational chemistry, few tools have achieved the ubiquity and respect of Multiwfn . Developed primarily by Dr. Tian Lu, this powerful wavefunction analyzer has become an essential utility for researchers working with Gaussian, ORCA, GAMESS, CP2K, and many other quantum chemistry packages. While newer versions are periodically released, Multiwfn 3.8 represents a significant milestone—a robust, widely-cited release that many workflows and tutorials still reference as a benchmark.
