Dear Tian
Thank you for your quick response. We are sure about the basis sets and the calculations. We have used the 6-311++G(d,p) for C, H, N, O and Cl- as well as Def2-TZVP for metal atoms. These basis sets have used for these interactions in literature. You have already said me that this term can be positive and negative in the EDA analysis. In fact, I want to know when the Eelectrostatic+exchange term can be positive or negative.  If there if a reason for that, please let me know.
Best Regards,
mehdi

Dear Tian,
We have investigated the interaction of Mn (M = Cu, Ag, and Au; n =1-4) nanoparticles with ChCl:Urea molecule. We have done the EDA using Multiwfn program. In the energy decomposition analysis of the complex (attached file), why the electrostatic+exchange repulsion terms are completely positive for the Au nanoparticles, while it is mostly negative for the Cu and Ag systems. What is structurally different among these systems that contribute to this trend.
Thank you in advance for the time you devote to answer my question.

Dear Admin,
I have plotted a RDG surface for my structure. We are considering the interaction of Choline chloride (ChCl):Urea complex with Ag, Au and Cu clusters. I know that the interaction between the Cl- anion in the ChCl:Urea complex with nanoclusters is attractive in nature (blue color or electrostatic interaction, whereas we can see some red colors (repulsive force). I appreciate if you give us a reasonable explanation for seeing the red observation?

Dear Admin,
I calculated the ΔEtot, ΔEorb and ΔEsteric as follows:
ΔEtot= -387.98
ΔEorb= -373.24
ΔEsteric = -14.74
I think ΔEsteric should be positive, while i have calculated it with negative value. Am i right? How is the sign of ΔEdis in energy decomposition analysis?

Dear Admin,
Thank you so much for your quick reply. I used the last version of Multiwfn 3.7. Unfortunately, I see the error again. The input file was too large. Thus, the file was divided into seven sections. Please use the seven links below, download the files, put them in a folder and extract. I appreciate if you see the error.

Dear Admin
I am doing energy decomposition analysis using the section”4.100.8 Perform simple energy decomposition by using combined fragment wavefunctions” in Multiwfn package.
I run a single point calculation with Gaussian09, revision A.02. My input file contains fragment-combined wavefunction as initial guess. Part of my input file is as follows:
When I run this input file, I receive an error (Error termination via Lnk1e in C:\G09W\l401.exe
). Could you please kindly guide me in this problem? I appreciate in advance for the time you devote to answer my question.
