What is the meaning of, e.g., XCXC, is the second X connected to the 1st or 2nd carbon? Or maybe it doesn't matter?
There was a problem hiding this comment.
The notation for (bidentate) adsorbates is a little tricky and there is no real consensus in the literature. I always place the adsorption site (the 'X') on the left side of the adatom, e.g. XC means that a carbon atom is bonded to the surface and XCXC means that the first and the second carbon atom have a bond to the surface. That said, CXCX or XCCX would be perfectly fine, too. I add some text to explain my notation.

since we know that atom1 is a surface atom, then if atom3.is_carbon() is True, we also know that atom1 is not atom3, so I think we can remove the atom1 is not atom3 check for better readability and maintenance. Same for atom2 is not atom4 below.

I agree and removed the check

I'm not sure regarding returning here. If we'll case about tridentates in the future, then this function will not explore all paths. Maybe OK to just use the return at the end? Are we worried that otherwise it'll be expensive?
(same comment for the function below)

Thanks for the hint. I think it is fine to use return only at the end.

perhaps we're missing an if atom2.is_carbon() before this loop

Yep, that is missing.

This if atom2 is not atom4 condition is very important, but I think we should remove all other if atom_X is not atom_Y checks for better readability and maintenance

we also return True if the molecule is tridentate. Would we like to reflect that in the docstring (if not in the function name)?

Good catch. I renamed the function to is_multidentate since all multidentate species can have resonance.

A base case example would help understanding (and good to also keep the preset example as well)

What do you mean? I thought XCHCHXC: [X]#CC=C[X] <=> [X]=C=CC=[X] was the example.

It's a bit confusing for me that X is not always listed at the end. Is this customary?

Unfortunately, the notation for adsorbates is a little confusing since it is difficult to represent the adsorbate structure as a string of letters. This is the current notation that we and some other groups use.

Consider turning these four nested if conditions into a single if condition with and in between.
Not a strong recommendation though, if you think the and version will be less readable, then OK to keep the nested version

Do you think this pathway could also be valid if bond_23 is double?
If I apply the recipe for
X1 {D/T} C2 {S} C3 {D/T} C4 {S/D} X5
I get
X1 {S/D} C2 {D} C3 {S/D} C4 {D/T} X5
reversing the atom labels this is:
X1 {D/T} C2 {S/D} C3 {D} C4 {S/D} X5
I expected that the 3rd line will be identical to the 1st line, since the recipe could be equally applied for it as well.
So maybe we should check for these bonds to get a mirror image:
X1 {D/T} C2 {S/D} C3 {D/T} C4 {S/D} X5

Thanks, Alon. You are right, bond_23 could also be a double bond. I changed the if statement.

Thank you for the thorough review, Alon. I incorporated all your comments. Also, the functions |

Motivation or Problem
Adsorbate molecules can exhibit resonance similar to gas-phase molecules. For example, the bidentate adsorbate XCXC (where X is a surface site) has the following three configurations:
[X]C#C[X] <-> [X]#CC#[X] <-> [X]=C=C=[X]
Currently, RMG cannot identify resonance structures for adsorbates.
In this pull request, I made the first step and added functions for the generation of resonance structures for adsorbates.
Description of Changes
Resonance occurs only for adsorbates that have at least two binding sites, also known as bidentate adsorbates.
Therefore, a function was added to molecule.py to check if an adsorbate has two binding sites.
The pathfinder.py was updated with functions to find the structures of adsorbates which can eventually have resonance structures. The structures that are searched for in the adsorbates are X-C-C-X and X-C-C-C-X.
Five types of resonance for adsorbates were added to resonance.py. The identified and implemented resonance types are as follows:
Apologies for the funky names of the resonance types. Resonance has not really been discussed in catalysis yet.
This pull request is work in progress and requires more changes to the source code. This is meant to start the discussion on resonance for adsorbates.
Testing
I have tested the functionalities of the added resonance functions by providing various adsorbates with and without resonance and confirmed that the functions work properly.
An RMG run for an catalytic system completed also without any errors.
Reviewer Tips
Use the functions in a standalone Jupyter notebook and see if RMG can identify the resonance structures correctly. A selection of bidentate adsorbates with resonance is: "XCXC, XCHXCH, XCXCH, XCXCCH2, XCHXCCH2, XCHXCXC, XCHXCXCH, XCHCXC, XCHCHXC, XCHCHXCH" where X is a surface atom.
Open Tasks
A function is required to generate the resonance structures for bidentate format (XOC(H)XO) and bicarbonate (XOC(OH)XO). Adding resonance generation for the formate case requires more changes to RMG to handle 'van der Waals' bonds. These changes are going to be part of another pull request.
