The easiest and most recommended way: Boot up Multiwfn, load .fch file produced by Gaussian or PSI4, then input
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)
Dear friends, I'm new to the forum, sorry in advance if I make any mistakes.
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,
