Require birad_r_recombination to be between a doublet and triplet #662

The Birad_R_Recombination family seems to be intended for recombination of a doublet R radical and a triplet biradical with opposite spin, producing a doublet radical.

Ex. image

Currently, the family also allows a similar recombination between two triplets.

Ex. image

These triplets must have opposite spin to form a bond, forming an overall singlet. However, RMG calculates the multiplicity based on the number of unpaired electrons (2) + 1. It is not clear to me yet how RMG should represent singlet diradicals. Two options are

  • Change the Molecule().update() function to assign multiplicity for these species correctly. Their adjacency lists are identical apart from the multiplicity, so this would require inputting information about the reaction producing the diradical. This issue will only be an issue for some families so this might not be a bad option.
  • Represent singlet diradicals with a closed shell structure. This requires some code to interconvert between the singlet diradical and closed shell structures to generate reactions.

image <=> image

For now, I suggest limiting this reaction family to triplet doublet recombinations.

Disproportionation between two triplets seems to be broken as well.
For a triplet and doublet, here is an example...
O(T) + H2NO(D) <=> OH(D) + HN=O(S)
For a triplet and triplet, I would expect to see...
O(T) + HNO(T) <=> OH(D) + [N]=O(D)

Interestingly, the H_abstraction family gives the following reaction which assumes the spin of both triplets is the same.
O(T) + HNO(T) <=> OH(D) + [N]=O(Q)
even though the quartet should not have a double bond.

For disproportionation, I just made changes to allow atom *2 in the template to have an unpaired electron, which may be the case for triplet-triplet disproportionation reactions. This allows reactions like the example in the last comment.
O(T) + HNO(T) <=> OH(D) + [N]=O(D)

The latest change to the disproportionation family has messed with the trees used for estimation. I think we will need to re-build the tree... or maybe only add the unpaired electron option to the root?

I wrote the following function to generate all possible singlet diradicals without radical centers on neighboring atoms from a singlet molecule (must have a pi bond)

def generate_singlet_diradicals(m: Molecule):
    for i in range(len(m.atoms)):
        m.atoms[i].id = i
    
    singlet_diradicals = [] 
    for edge in m.get_all_edges():
        
        M = m.copy(deep=True) 
        if edge.get_order_num() > 1: # find a pi bond
            atom1_id = edge.atom1.id
            atom2_id = edge.atom2.id
            M.atoms[atom1_id].increment_radical()  # add a radical to each atom of the pi bond

This function can take in a singlet diradical and choose the best closed shell singlet representation...

def generate_closed_shell_singlet(m: Molecule):
    for i in range(len(m.atoms)):
            m.atoms[i].id = i
    assert m.multiplicity == 1 and m.get_radical_count()>0
    radical_center_ids = [x.id for x in m.atoms if x.radical_electrons > 0]
    # remove radicals from radical centers (2)
    for radical_center_id in radical_center_ids:
        m.atoms[radical_center_id].decrement_radical()
    # add removed radicals (2) to one of the radical sites as a lone pair (1)
    m.atoms[radical_center_ids[0]].increment_lone_pairs()
    # pick the best resonance structure
    return m.generate_resonance_structures()[0]

Disproportionation between two triplets seems to be broken as well. For a triplet and doublet, here is an example... O(T) + H2NO(D) <=> OH(D) + HN=O(S) For a triplet and triplet, I would expect to see... O(T) + HNO(T) <=> OH(D) + [N]=O(D)

Interestingly, the H_abstraction family gives the following reaction which assumes the spin of both triplets is the same. O(T) + HNO(T) <=> OH(D) + [N]=O(Q) even though the quartet should not have a double bond.

@donerancl Hi Anna. Thanks for these insights! I am curious about the reasons why we need to let RMG consider triplet diradical + triplet diradical <=> doublet R + doublet R. I've noticed the current RMG model rarely include triplet diradical + triplet diradical reactions, apart from serveral clearly incorrect HNO(T) reactions, like HNO(S)+HNO(S)(+M)=HNO(T)+HNO(T)(+M). Is the consideration of this type of reaction driven by its importance as stated in theoretical literature? Thanks.

@ChgCao Hi Chuangchuang. Thanks for the comment. I think you are right that the triplet diradical + triplet diradical reactions are rarely important, since we expect both concentrations to be small. I think the issue is that there isn't much consistency between how families treat them. I worry if triplet-triplet reactions are allowed by some families (like H_abstraction, Birad_R_Recombination) and not by others (like Disproportionation), the edge will be lopsided. The pressure dependent HNO(S) + HNO(S) <=> HNO(T) + HNO(T) net reaction you mention is technically spin-allowed, although surely very slow in the forward direction (~40 kcal/mol endothermic) and unimportant in the reverse direction due to low concentrations of HNO(T). I also wonder if the importance of HNO(T) has been overestimated due to some of the spin conservation bugs we have found in the code. Maybe we don't need to worry about it as much like you say.
