Positive-charge scavenging by amines in pulse-irradiated sec-butyl chloride glasses at 77 K. Dependence of rate on the ionization potential of amines

Free electron transfer mirrors rotational conformers of substituted aromatics: Reaction of benzyltrimethylsilanes with n-butyl chloride parent radical cations

“…In order to interprete the decay of the benzyltrimethylsilane type radical cations two reactions are to be considered. Dinnocenzo et al 3,4 gave convincing arguments for a nucleophile driven bimolecular decay (14).…”

“…Hence the pulse radiolysis of n-butyl chloride generates mainly the following transients, cf. reaction (5): 13,14…”

“…In the pulse radiolysis of pure n-butyl chloride, the optical transient absorption spectrum exhibits a broad absorption band between 350 and 650 nm (l max ¼ 500 nm) of the parent ion n-C 4 H 9 Cl þ with a life time t ¼ 140 ns. 13,14 Adding to the sample millimolar concentrations of the silanes 1 and 2 shortens t due to a pseudo-first order reaction. In the course of this reaction (6), product transient spectra appear (see Fig.…”

Trapped-electron capture by steroid molecules with two distinct, reactive groups. A test of the long-range tunneling mechanism

“…where values of = (R,•2 -R¡2 + a2)/2a, i ^j, are the perpendicular distances to the plane of intersection of the two spheres. In case 3 one sphere completely engulfs the other, and for Rx > R2 + 0 = V1/iV1 + V2) Pn = Px (14) If, however, the two acceptor units are linked so that they are at a fixed separation a, the probability of a trapped electron surviving at time t is P"(t) = exp[-cVn(f)] (8) where now Vn(t) is the net capture volume (excluding overlap) for the difunctional species. It is convenient to…”

Carbon σ-Electron Densities and C-H Stretching Vibration Frequencies of Phenanthrene

“…Langhoff [2] and Ling et al [3] studied its spectrum theoretically, applying quantum mechanical methods. The phenanthrene radical cation was generated through γ-irradiation of the neutral molecule [4,5] or of the molecule in an isolation matrix [6]. It is known to undergo electron transfer reactions [7,8].…”
