Effect of molecular structure of nitroalkanes on the C-NO2 bond strength and activation energy of the gas-phase radical decomposition according to the quantum-chemical simulation
Abstract:The non-empirical (MP2 and CCSD), composite (G4), and DFT (B3LYP, CAM-B3LYP, B98, and wB97XD) methods with different basis sets have been employed to compute the formation enthalpies of a series of C 1 -C 4 nitroalkanes and the hydrocarbon radicals formed via the C-N bond rupture as well as the C-N bond dissociation energies. For the series of isomeric nitroalkanes, the effects of the nature of the participating carbon atom (primary, secondary, or tertiary) and the size of adjacent alkyl group on the C-N bond … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
