I am not sure, please search "NLMO" in the NBO manual corresponding to the NBO version you are using to try to find keyword to bypass NLMO analysis, or you can send E-mail to NBO developer to ask for help.

Dear Professor Lu
Thanks for your reply
You can help change keywords NLMO?
best regards

If you do not need to perform NLMO analysis, change your keywords to avoiding doing this. It seems that NLMO iteration is in progress, while the cost is quite high.

Dear Dr. Tian Lu,

I took your advice and purchased NBO7.

Thank you for your assistance!

Dear Eugene,

Unfortunately, it is not possible to write Fock matrix into .47 file generated by Multiwfn.
Multiwfn currently can generate .47 file only when all basis functions are Cartesian type, while although you can use "%output Print [P_Iter_F] 1 end" keyword in ORCA to print out Fock matrix, it is based on spherical-harmonic basis functions.

If you have to use ORCA in combination NBO, you can buy a copy of NBO 7, it is not quite expensive (100 USD for academic user).

Best,

Tian

Dear Dr. Tian Lu
I study non-covalent interactions, so I need to calculate the NBO analysis of E2. For calculations, I use Orca 4.2.0 and Multiwfn_3.7 jun.
According to the Multiwfn manual, the Orca wave function in the .gbw file can be converted to * 47 format for GENNBO. However, the resulting file *47 does not contain the% FOCK section for calculating E2, and the resulting files *31-42 cause the Multiwfn to crash.
I also used the Molden2AIM- https://github.com/zorkzou/Molden2AIM to generate 47 files, but the program reports errors in the formation of the Fock matrix. NBO graphic files are also not readable by Multiwfn.
"
Sum of MO Occupancies = 824.0000000000
Analytically integrated number of electrons = 824.0000001527
Difference = 0.0000001527
Difference per atom = 0.0000000014
Error of orthogonality in C^T * S * C - I = 0.0004543759 (o)
0.0006991327 (d)
### Warning! ChkOrtho fails.
Do not use the $FOCK data for Second-Order Perturbation Theory analysis. "

Unfortunately, files larger than 5 MB are therefore unable to attach to my message.

Please tell me, is it possible to get the Fock matrix from Orca using Multiwfn?

Are there any ways to get the *47 file from the wave function without recounting?
Thank you in advance for your answers.
