The factors that control the reactivities of aryl radicals toward hydrogen-atom donors were studied by using a dual-cell Fourier-transform ion cyclotron resonance mass spectrometer (FT � ICR). Hydrogen-atom abstraction reaction efficiencies for two substrates, cyclohexane and isopropanol, were measured for twenty-three structurally ...

The development of efficient carbon atom sources was carried out concurrently with studying reactions 1--3, and we already have intriguing results concerning these reactions, even though the development phase is still in progress. Our goals are to study reactions of carbon atoms with hydrogen, hydrogen chloride, ...

Quantum and quasiclassical state-to-state dynamics for the NH + H' reaction at high collision energies up to 1.6 eV was studied on an accurate ab initio potential energy surface. Both of the endothermic abstraction (NH + H' ? N + HH') and thermoneutral exchange (NH + H' ? H + NH') channels were investigated from the same set of wave packets using an ...

ABSTRACT: The weighted stochastic simulation algorithm (wSSA) recently developed by Kuwahara and Mura and the refined wSSA proposed by Gillespie et al. based on the importance sampling technique open the door for efficient estimation of the probability of rare events in biochemical reaction systems. In this paper, we first apply the ...

/sup 75/Ge recoils are made using the (n,2n) reaction. By analogy with Si recoils, two divalent species are suggested as intermediates in the recoil-germane reaction, one formed by H abstraction and the other formed by insertion only. A series of moderator and competition experiments were conducted. Of the noble gases, Kr is the most ...

Methanol and 2-propanol solutions of hydroxymaleimide were irradiated with ?-ray and mechanism of its ?-irradiation-induced reactions was investigated through final-product analyses using high performance liquid chromatography (HPLC) coupled with mass spectroscopy. An addition reaction of a solvent radical toward hydroxymaleimide was dominant among its ...
