The Importance of Thermodynamic Data for Pyrrole Pyrolysis and Combustion Chemistry. [PDF]

Chemphyschem
High level ab initio quantum chemical computations with ORCA 6.1.1 are done to derive enthalpy and entropy of formation at 298.15 K for 32 species that include both radicals and stable molecules relevant to the pyrolysis and combustion of pyrrole. The effects of thermochemical data on chemical model performance are assessed.
