CCL:G: Gaussian SCRF error "No solvent atoms in DisRep"



Dear all,

I got the answer from Gaussian, Inc., and it is below.

Hello Igors,
Thank you for giving us a chance to comment.

The problem is that you have "Dis Rep Cav", which are non-electrostatic terms included in the G03 PCM models for the final energy. However, only limited number of solvents are defined (as in G03) and limited number of elements are available. For example, n,n-DiMethylFormamide is not available in G03.

Please remove "Dis Rep Cav" and it should be fine.

If we read between the lines, this probably means "please use SMD and not obsolete methods, if You care about non-electrostatic interactions".
For me, the reason to use
Dis Rep Cav was so that I can use the low-cost CPCM instead of presumably high-cost IEFPCM mentioned as the basis for SMD in G09 Reference (these considerations were based on previous experience by the senior lab staff). However, I did not manage to note that "SMD" is in fact "an option to PCM calculations", so now I did p-nitroaniline in DCM solution with SCRF=(CPCM,SMD,Solvent=…), as well as with SCRF=(IEFPCM,SMD,Solvent=…), with the following results:
1. Both route sections did not bring about any errors
2. IEFPCM calculation actually lasted almost a minute less than CPCM one (2:7 vs. 2:53 minutes).
3. Error on polarization charges was 0.016 for IEFPCM and 0.306 for CPCM.

So now I at least understand why CPCM is not suggested by Gaussian, Inc. staff. Thanks to Dr. Zou for the comment and to

Zhiqiang Zhang for raising the issue!

Dear all,

I have encountered the same problem when trying to use DMFA with SCRF=Read (in my case, also Dis Rep, along with Cav and Surface=SAS). Also Gaussian 09, rev. D.01. It seems to me that N,N-DMFA is not completely defined in this version? I postponed writing to Gaussian, Inc., but I will do it now as other people have the same issue, if nobody reports here today.

 Hi all,
 I am doing calculation with solvent and get the error "No solvent atoms in
 DisRep" at the end. I am trying
 to include the dispersion and repulsion correction in my calculation.
 My input file:

 The last two lines of the log files:
 No solvent atoms in DisRep.

 Does anybody know how to resolve this issue?
