Dear all, I am using mesmer to simulate the reaction of R radicals with O2 and subsequent reactions in the atmosphere, and the simulation process is as shown in the following figure. The calculation shows an error “WARNING: Chemically significant eigenvalues (CSE) not well separated from internal energy relaxation eigenvals (IEREs). The last CSE = -3.10654e+08 and the first IERE = -1.70469e+09 (last CSE)/(first IERE) ratio = 0.182235, which is less than an order of magnitude Results obtained from...
