3.7 Aug 14, 2020 New Release
3.6 May 21, 2019 New Release A very powerful and easy-to-use RESP module is added into main function 7 (Population analysis). It can calculate the well-known ElectroStatic Potential (RESP) charge proposed in J. Phys. Chem., 97, 10269 (1993), and can also calculate ESP fitting charges under various customized conditions such as atomic equivalence constraint and fragment charge constraint. Multiple conformation is fully supported. See Section 3.9.16 for detailed introduction and Section 4.7.7 for examples. This module should be able to bring a revolution in the field of RESP charge derivation.
Energy decomposition analysis based on UFF/AMBER/GAFF molecular forcefield is supported as subfunction 1 of main function 21. See corresponding introduction in Section 3.24.1 and examples in Section 4.21.1 of the manual.
2.4 May 23, 2012 New Release · Fixed a bug introduced by Version 2.2.1 (that is Multiwfn crashes during reading the .fch files produced by unrestricted calculation with cartesian basis functions)
· Fixed a bug in the interface for selecting the interbasin surfaces to be generated
· A serious bug in reading the .fch files produced by unrestricted calculation with spherical basis functions is solved
· Merz-Kollmann charge is supported in population module
· Option 10 is added to topology analysis module, this is a small tool used to calculate Shannon aromaticity index
