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

Hello Igors,

One thing to add is that SMD is a solvation model (IEFPCM using SMD radii for electrostatic part, plus nonelectrostatic terms), so please do not combine SMD with other solvation models. The program should have recognized this error and abort, thank you for catching the bug.

As for the cost, please rest assured that difference between IEFPCM and CPCM will be minor for most calculations. The only exception is that for very large molecules with hundreds of atoms, more MEMORY (RAM) is required for IEFPCM than CPCM.

Hi Zhiqiang,

Yes, I got that, but notice Dr. Zou writes about G03 PCM models. It definitely means Gaussian, Inc. people are considering manual definition of Dis Rep Cav as something truly outdated, so that they did not update the list for G09 and G16. Whereas both epsilons and SMD parameters are there for all solvents listed in the manual.

So we can probably look for the list of changes between G03 and G09 to check if the solvent we need has these parameters defined. In G03 Reference, only 24 solvents are listed as parametrized ones (neither DMFA, nor AcOH is there), whereas in G09 Reference there are 184 ones, with those 24 going as first. I consider therefore that all those 160 solvents cannot be used with Dis Rep Cav… I checked for CarbonDiSulfide and NitroBenzene – they both produce the same error,
No solvent atoms in DisRep.
Some of these solvents quite obviously are not augmentable with non-electrostatics (e.g., Xylene-mixture), though :)

With best wishes,

Hi Igors,


Thank you for sharing this comment. In my understanding, the comment from Gaussian, Inc. staff means not all the solvents available in their database (like n,n-DiMethylFormamide in your case) are defined for “Dis Rep Cav” calculation. This is information is not very clear in the G09 manual on their website. Maybe this is an obsolete method as you mentioned and we can use SMD to get the results.

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.
