12
6
Then you can find vdW volume (enclosed by isosurface of electron density of 0.001 a.u.) on screen, for example:
Volume:   177.09407 Bohr^3  (  26.24263 Angstrom^3)

Could you kindly guide me on how to calculate the volume of a molecule using the Multiwfn software?

How could I calculate the volume of a methane molecule, for example, using outputs from the Gaussian or psi4 software?

Could you kindly provide me with an example for this task?

Thanks in advance.

Best regards,
