Three possible pathways for hydrogen abstraction from CH3CH2SH by the OH radical: (a) abstraction from the -CH2 group, (b) abstraction from the -SH group, and (c) abstraction from the -CH3 group. All geometries are optimized using the M06-2X/def2- TZVP level of theory, with energies calculated at CCSD(T)/CBS, including zero-point energy (ZPVE) corrections at M06-2X/def2- TZVP. The ... represent bond formation and cleavage processes, with significant bond lengths indicated in Å. The atom color scheme is consistent throughout the paper and is illustrated separately for reference. -- astro-ph.GA
