Hydrogen Abstraction/Addition Reactions in Soot Surface Growth [PDF]
Physical Chemistry Chemical Physics, 2020 The hydrogen abstraction (HB) and addition reactions (HD) by H radicals are examined on a series of polycyclic aromatic hydrocarbon (PAH) monomers and models of quasi-surfaces using quasi-classical trajectory (QCT) method. The QCT results reproduce the rate constants of HB reactions on PAH monomers from density function theory (DFT) in the range of ...

Hydrogen‐Abstraction/Acetylene‐Addition Exposed [PDF]
Angewandte Chemie International Edition, 2016 AbstractPolycyclic aromatic hydrocarbons (PAHs) are omnipresent in the interstellar medium (ISM) and also in carbonaceous meteorites (CM) such as Murchison. However, the basic reaction routes leading to the formation of even the simplest PAH—naphthalene (C10H8)—via the hydrogen‐abstraction/acetylene‐addition (HACA) mechanism still remain ambiguous ...
