Version 3.3 (2014-Apr-14)
  • Subfunction 20 is added to main function 100. This new function is used to parse the output of (hyper)polarizability task of Gaussian09 and then print them in a much more readable format, and at the same time some quantities relating to (hyper)polarizability analysis will be outputted. See Section 3.100.20 of the manual for detail.
  • Subfunction 19 is added to main function 100, which can generate promolecular .wfn file based on fragment wavefunctions, see Section 3.100.19 for introduction and Section 4.100.19 for illustrative examples.
  • Fingerprint plot analysis (defined in the framework of Hirshfeld surface analysis) is fully supported in main function 12. See Section 4.12.6 for example and Section 3.15.5 for introduction. This function is very useful for analyzing non-covalent interaction in molecular crystal.
  • Subfunction 6 is added to main function 200, which is used to analyze correspondence between orbitals in two wavefunctions. See Section 3.200.6 for introduction and example. By this function for example you can know the conversion relationship between the MOs calculated at HF/6-31G* level and that calculated at B3LYP/cc-pVTZ level, or obtain the knowledge about how the MOs produced by HF are related to the natural orbitals produced by post-HF methods.
  • Promolecular approximation of reduced density gradient (RDG) and sign(lambda2)rho now supports all elements from H to Rn (in older versions this feature only supports H~Ar).
  • In the spectrum plot module (main function 11), the contribution of individual transitions to the total spectrum can be outputted by option 15, this feature is particularly useful for identifying the nature of total spectrum. See Section 4.11.2 of the manual for example. In the meantime, option 16 is added, which is used to locate the positions of minima and maxima of the spectrum.

  • The rule for locating settings.ini file is changed. In current version, Multiwfn tries to find and use this file in current folder, if it is not presented, the settings.ini in the path defined by "Multiwfnpath" environment variable will be used (if still missing, default settings will be employed instead).
  • Deformation density now and be integrated in fuzzy atomic space (via option 1 of fuzzy space analysis module) and AIM basin (via option 7 in basin analysis module).

Multiwfn is the most powerful wavefunction analysis program, supporting almost all of the most important wavefunction analysis methods. Multiwfn is free, open-source, high-efficient, very user-friendly and flexible. Windows (32/64bit XP/Vista/7/8), 64bit Linux and Mac OS X platforms are supported. The latest version can be downloaded at Multiwfn website Multiwfn accepts several kinds of files for inputting wavefunction information: .wfn/.wfx (Conventional / Extended PROAIM wavefunction file), .molden (Molden input file), .31~.40 (NBO plot file), .fch (Gaussian formatted check file). Other file types such as Gaussian .cub file, DMol3 .grd file, .pdb, .xyz file and plain text file are acceptable for specific functions.
  • Special points of Multiwfn
    • (1) Comprehensive functions. Almost all of the most important wavefunction analysis methods (except for NBO methods) are supported by Multiwfn.
    • (2) Very user-friendly. Multiwfn is designed as an interactive program, prompts shown in each step clearly instructs users what should do next, Multiwfn also never print obscure messages, hence there is no any barrier even for beginners. Besides, there are more than fifty tutorials in the manual, which would be very helpful for new users.
    • (3) High efficiency. The code of Multiwfn is substantially optimized. Most parts are parallelized by OpenMP technology. For time-consuming tasks, the efficiency of Multiwfn exceeds analogous programs significantly. Meanwhile, the memory requirement is very low.
    • (4) Results can be visualized directly. A high-level graphical library DISLIN is invoked internally and automatically by Multiwfn for visualizing results, most of plotting parameters are controllable in an interactive interface. Thus the procedure of wavefunction analysis is remarkably simplified, especially for studying distribution of real space functions.
  • Primary functions of Multiwfn
    • 1) Showing molecular structure and viewing orbitals (MO, NBO, natural orbital, etc.).
    • 2) Outputting all supported real space functions at a point.
    • 3) Outputting real space function in a line and plot it as curve map.
    • 4) Outputting real space function in a plane and plot it as graph. Supported graph types include filled-color map, contour map, relief map (with/without projection), gradient map, vector field map.
    • 5) Outputting real space function in a spatial scope, data can be exported to Gaussian-type grid file (.cub) and can be visualized as isosurface.
    • 6) For the calculation of real space functions in one-, two- and three-dimensions, user can define the operations between the data generated from multiple wavefunction files. Therefore one can calculate and plot such as Fukui function, dual descriptor and density difference very easily. Meanwhile promolecule and deformation properties for all real space functions can be calculated directly.
    • 7) Topology analysis for electron density (AIM analysis), Laplacian, ELF/LOL etc. Critical points and gradient paths can be searched and visualized in terms of 3D or plane graph. Interbasin surfaces can be drawn. Values of real space functions can be calculated at critical points or along topology paths.
    • 8) Checking and modifying wavefunction. For example print orbital and basis function information, manually set orbital occupation number and type, translate and duplicate system, discard wavefunction information from specified atoms.
    • 9) Population analysis. Hirshfeld, VDD, Mulliken, Löwdin, Modified MPA (including three methods: SCPA, Stout & Politzer, Bickelhaupt), Becke, ADCH (Atomic dipole moment corrected Hirshfeld), CHELPG, Merz-Kollmann and AIM methods are supported.
    • 10) Orbital composition analysis. Mulliken, Stout & Politzer, SCPA, Hirshfeld, Becke and natural atomic orbital (NAO) methods are supported to obtain orbital composition.
    • 11) Bond order analysis. Mayer bond order, multi-center bond order (up to 10-centers), Wiberg bond order in Löwdin orthogonalized basis and Mulliken bond order are supported. Mayer and Mulliken bond order can be decomposed to orbital contributions.
    • 12) Plotting Total/Partial/Overlap population density-of-states (DOS).
    • 13) Plotting IR/Raman/UV-Vis/ECD/VCD spectrum. Abundant parameters (broadening function, FWHM, etc.) can be determined by users, individual contribution from each transition to the spectrum can be studied.
    • 14) Quantitative analysis of molecular surface. Surface properties such as surface area, enclosed volume, average value and std. of mapped functions can be computed for the whole molecular surface or for local surface; local minima and maxima of mapped functions on the surface can be located. Becke and Hirshfeld surface analysis are also supported.
    • 15) Processing grid data (can be loaded from .cub/.grd or generated by Multiwfn). User can perform mathematical operations on grid data, set value in certain range, extract data in specified plane, plot integral curve, etc.
    • 16) Adaptive natural density partitioning (AdNDP) analysis. The interface is interactive and the AdNDP orbitals can be visualized directly.
    • 17) Analyzing real space functions in fuzzy atomic spaces (defined by Becke or Hirshfeld). Integral of selected real space function in atomic spaces or in overlap regions of atomic spaces, atomic multipole moments, atomic overlap matrix (AOM), localization and delocalization index (DI), condensed linear response kernel, multi-center DI, as well as four aromaticity indices, namely FLU, FLU-pi, PDI and PLR can be computed.
    • 18) Charge decomposition analysis (CDA) and extended CDA analysis. Orbital interaction diagram can be plotted. Infinite number of fragments can be defined.
