Dear Professor
When calculating fukui(as section 4.22.1 in manuel) , in the current version(3.8), there are no 7, 10 and 16 options after the 100 command as below. Can you fix it?
.
.
.
.
Boot up Multiwfn and input below commands:
examples\phenol.xyz
100 // Other functions (Part 1)
16 // Calculate various quantities in conceptual density functional theory
1 // Generate .wfn files for N, N+1, N-1 electrons states
.

Thank you Dear Prefessor
I know what you said, but it takes hours to open vmd xyz file at 100000 frames. How to do it differently from VMD?
Hi
How to convert output trajectory(Molecular_dynamic.xyz file) to pdb format?

Dear Professor
Thank you very much for your help and update

Can you help me on how to do this? how to get lattice vectors?
α=γ=90°, β=103°
a=21 b=11 and c=19 angstrom

The unit cell lengths of the cubic structure were entered as above. But if the structure is not cubic, How to enter the angle values of the unit cell for a monoclinic structure(α=γ=90°≠β)?

Dear Professor;
You contribute a lot to science and scientists. Really sincerely thank you very much. I want to ask one last thing about this subject. My molden file has 2 atoms Oxygen and Hydrogen. Could you provide some information on what is the [Nval] specified in the multiwfn manual. Also, are the numbers next to the O and H atoms (6 for O and 1 for H) the number of valence electrons?And did I write these numbers correctly?

Dear Professor
I calculated cp for vmd using the diamond_222.molden file and as in your video (https://www.youtube.com/watch?v=mgsnhvWH5SI), but the vmd opened molecule was not periodic. I chose the x, y and z coordinates, but the periodic molecules did not form.
Best regards
Dear Professor
I will calculate the aim topology, that is, BCP (bond critic point), using the ''diamond_222.molden'' file as in Section 4.2. Is there any need to convert the "diamond_222.molden" file to the "NO_0001.mwfn'' file for this? so we can't use diamond_222.molden file for BCP (bond critic point) calculation as Section 4.2?
Best Regards
Dear Professor, thank you for reply
''Next, we need to generate a wavefunction file containing natural orbitals of the excited state of interest. Boot up Multiwfn and input
diamond_222.molden
18 // Electron excitation analysis
13 // Generate natural orbitals of excited states
diamond_222.out
1 // The excited state of interest is assumed to be the first excited state
[Press ENTER button] // Use 0.25 Bohr of grid spacing to generate overlap matrix''
Is the cp obtained by this method valid for a periodic system or for an isolated molecule in the gas phase?
Best regards
Dear Prefessor
Many thanks for this information. I can calculate an organic molecule with multiwfn. In line with the information you have given above, will I have periodically made a PBC calculation using the calculations in section 4.2 of the NO_0001.mwfn file that I obtained with cp2k (using PBC=periyodic boundry condidation)?

I ask this question independently of ESP. Many articles are described differently.
So,is the following conclusion correct for Fukui functions?
F+→ easily undergo nukleophilic attack (i.e. nukleophilic reagents tend to interact with this site)
F-→ easily undergo electrophilic attack (i.e. electrophilic reagents tend to interact with this site)
Hello Professsor Tian Lu
Which of the following(1 or 2) is true that relationship between the red and blue regions of the MEP map and the fukui functions?
1. Red colour areas: electronically rich→nucleophile (proton-loving)→nucleophilic attack→f+ (fukui) values are positive and high
Blue colour areas: electronically poor→electrophile (electron-loving)→electrophilic attack→f- (fukui) values are positive and high
Or
2. Red colour areas: electronically rich→nucleophile (proton-loving)→electrophilic attack→f- (fukui) values are positive and high
Blue colour areas: electronically poor→electrophile (electron-loving)→nucleophilic attack→f+ (fukui) values are positive and high

Thank you very much Professsor Tian Lu
Thank you for reply Professsor Tian Lu. Do you have an article about ICSS and NICS calculating (section ''4.200.4 Study iso-chemical shielding surface (ICSS) and magnetic shielding distribution' in multiwfn manual')?
Best Regard
Hello Professsor Tian Lu
I want to use some information in your multiwfn manual in my article. Can you suggest an your article that I will give reference my article?
Best Regard
Dear Professor Tian Lu
After reviewing this video thoroughly, I succeeded.
Thank you for reply

Thank you. Can you suggest an article or yours containing the correct formulas in Section 4.7.3 for me to cite?

Hello Dear
The formulas for f+,f- which is many articles and multiwfn manual;
f+= q(N+1)− qN and f-= q(N)− q(N-1) (page 387 in multiwfn manual) (1. Eq.) (N=charge 0, N+1=charge-1, N-1= charge+1)
Fuki calculation is given below in section ''Calculating global and atomic indices ''(page 679) in multiwfn manual
Units used below are "e" (elementary charge)
Atom q(N) q(N+1) q(N-1) f- f+ f0 CDD
1(C ) -0.0587 -0.1185 0.0852 0.1439 0.0598 0.1018 -0.0841
2(C ) -0.0390 -0.1674 0.0268 0.0658 0.1284 0.0971 0.0626
3(C ) -0.0597 -0.1873 0.0319 0.0916 0.1276 0.1096 0.0360
If f+and f- are calculated for 1(C) according to equation 1;
f+= q(N+1)− qN=-0.1185-( -0.0587)=-0.0598
f-=q(N)− q(N-1)=-0.0587-0.0852=-0.1439
But obove the table are calculated as f+= 0.0598 and f-=0.1439 so Do these formulas must arranged as follows?
f+= qN(r)-q(N+1) (2. Eq.)
f- =q(N-1)-qN(r)
Which formula is correct for f+and f- (1. or 2. Eq.)?
Best regards
Thank you very much for helping very helpful again
