建议：

You must run Multiwfn from within its own directory or add it to your system PATH. Use cd C:\Multiwfn_3.8 first.

The Windows release is highly optimized, stable, and requires no auxiliary system path configuration to operate out of the box.

Securing a legitimate is a straightforward process if you follow the official channels. Remember: Open your browser and go to: : Adds

Subfunction 17 of main function 18 implements electron density polarization analysis based on electron excitations (originally proposed in J. Phys. Chem. A, 124, 633, 2020). This provides valuable insight into electron density polarization under external perturbations such as point charges and can be used to study substitution effects, electrophilic/nucleophilic reaction mechanisms, and atomic polarizability.

Supported, though, as noted in the manual, it is maintained via community contributions. Source Code: Available for compiling on other platforms.
