Description

It appears that some rate rules from Sharma et al. 2010, which are mentioned in the rate rules just with the text 'Sumathy CBS-Q calculations' did not have the degeneracy modified before they were input as rate rules. This leads RMG to mis-predict many of these reactions by a factor of 2 or 3.

This was confirmed for entry 798 which is methyl peroxyl isomerization. Ideally, these should be removed as rate rules and input as training reactions.

Research direction

Start with rate-rule entry 798, the methyl peroxyl isomerization case, and compare its degeneracy with the Sharma et al. 2010 source. Review other entries labeled “Sumathy CBS-Q calculations”; done means affected rules are identified and handled as training reactions rather than incorrect rate rules.
