Sounds great, from your description. A couple of thoughts.

I think this should be px too.

@kirkbadger18 or @bjkreitz please confirm if this is still an issue. We should resolve and merge this pull request soon

I changed p0 to px for (CR3OR)*

Looks good to me. The only cases of R with p0, besides line 1791, that I see left are the nitrogen containing nodes which I am working on.
I ran a mechanism with O2, H2, and CO, and they were basically identical. This PR did change the thermodynamic estimates of some species, I think for the better. Here, the estimate for the thermodynamics of XCOOH now comes from XCOH instead of an average of (XCH, XCCH3, XCOH, XCCHCH2, XCCH2CH3, XCCHO, XCCH2OH):
new:
old:
I also looked through three surface reaction families: Surface_Adsorbtion_Single, Surface_Dissociation, and Surface_Abstraction to see if p0 was used for R groups there. I did not see that this was an issue in those files. It is possible that it shows up here and there in other families, but at first glance it does not appear to be an issue.

Does this R get px as well? Also Rs for OROR on lines 178-179, and O-*OR on line 245?

Thanks Chris! I changed p0 to px for the C#*-R-C=*R, O-*OR, OROR

Thanks Bjarne and Chris and Kirk. I enabled automerge. It should go in once the unit tests pass. |

Description
The nodes in the adsorption correction file adsorptionPt111.py were rather restrictive. In most nodes it was specified that the general
Rcannot have lone pairsp0. I didn't pay close attention to this when I restructured the adsorption correction database because theRwas mostly C in the training data. However, this is not correct. In most cases, the R can also be replaced with O/N. Actually, in some cases the training data that I used contained O, but the node would not have been used to estimate the thermo for this species. @kirkbadger18 caught this detail.I revised now the adjacency lists and made the nodes more permissive, by changing the
p0topxwhenever it is reasonable.I did not touch the nodes containing nitrogen, because @kirkbadger18 is doing a complete overhaul of the nitrogen adsorption corrections.
Testing
I generated a mechanism for the oxidation of ethane on Pt(111) without (left log file) and with (right log file) these changes. The mechanisms are indeed slightly different.
With the more permissible adsorption corrections, RMG deems a bidentate carboxyl to be important
Previously, this species was discovered, but remained in the edge.
You see that the thermochemistry of the species has changed because RMG used the top level node
C*O*to estimate the thermo and now it uses the more specificC=*RO-*. Whether this species should exist is another story (because there is also a monodentate carboxyl). However, I think that these updates to the adsorption corrections are necessary since they can affect our thermo estimate for some species and make them (supposedly) more accurate.Review
Carefully review that I haven't missed a node or an
R. @kirkbadger18 will make another PR soon that changes the N-containing nodes.Generate a mechanism for system of your choice and check if everything works accordingly.
