Selective Hydrogen Atom Abstraction by Hydrogen Atoms in Photolysis and Radiolysis of Alkane Mixtures at 77 K [PDF]
Abstract A selective hydrogen atom abstraction reaction by H atoms, which are produced at 77K by radiolysis of alkane or photolysis of hydrogen halides, has been found in isobutane, 2,2,3,3-tetramethylbutane (TMB), and cyclopropane matrices as well as in the neopentane matrix. The selective hydrogen atom abstraction reaction is caused by

Ab initio chemical kinetics of Isopropyl acetate oxidation with OH radicals
Global reactivity descriptors of isopropyl acetate (IPA) and thermo-kinetic aspects of its oxidation via OH radicals have been studied. Transition state theory (TST) was utilized to estimate the bimolecular rate constants.

Abstraction of atomic hydrogen by atomic deuterium from an amorphous hydrogenated silicon surface [PDF]
We have studied the interactions of atomic deuterium with hydrogenated amorphous silicon (a-Si:H) surfaces using surface-sensitive infrared spectroscopy. We deconvoluted the effects of the abstraction reaction from insertion and etching reactions and determined the activation energy barrier for abstraction of H by D from a-Si:H surfaces.
