A definitive heat of vaporization of silicon through benchmark ab initio calculations on SiF_4 [PDF]
In order to resolve a significant uncertainty in the heat of vaporization of silicon -- a fundamental parameter in gas-phase thermochemistry -- $\Delta H^\circ_{f,0}$[Si(g)] has been determined from a thermochemical cycle involving the precisely known ...

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.
