Singlet O=O vdW species in Surface_Adsorption_Abstraction_vdW

As we discussed in #458, the gas phase O2 will be represented as [O][O], which has the following adjaceny list notation:

1 O u1 p2 {2,S}
2 O u1 p2 {1,S}

Since we don’t use the singlet O=O for the gas phase oxygen, do we want the vdW O2 to have this form in Surface_Adsorption_Abstraction_vdW family?

index = 11,

We didn’t add the forbidden entry O=O in Surface_Adsorption_Bidentate family as well, and the following reaction will be created:

For consistency, should we keep all of them or remove the O=O entry

Start by locating the Surface_Adsorption_Abstraction_vdW and Surface_Adsorption_Bidentate family definitions, then inspect the O=O entry at index 11 and the related forbidden-entry behavior. Compare these definitions with the [O][O] gas-phase representation and review the linked discussion and generated reaction example. Done means the project has a documented, consistent decision and the affected family entries reflect it.
