Anyone have experience with this molecule ([O]C[O]) 😆. RMG added in to my model through Pdep networks and my methane laminar flame speed for equivalence ratio of 1.2 went from 53 cm/s to 70 cm/s (for reference the experimental flame speed is high 30s)! I used the Klippenstein_Glarborg2016 as a seed mechanism. When I use 'FFCM1(-)', I get the same molecule in my model, but the flame speed does not shoot up.
