Solvent influence on the magnetic field effect of polymethylene-linked photogenerated radical ion pairs
TL;DR: In this article, the solvent viscosity and polarity dependence of the magnetic field effect in polymethylene-linked radical ion pairs, which were generated by photoinduced intramolecular electron transfer in compounds of the type pyrene-(CH2)n-N,Ndimethylaniline, has been studied.

Intersystem Crossing in Charge-Transfer Excited States†
TL;DR: In this article, the exact rate constants for intersystem crossing in exciplexes formed between cyanoanthracenes as acceptors and alkylbenzenes as donors in solvents with low to moderate polarity have been measured.

Orbital interactions and long-range electron transfer
TL;DR: In the early 1970s, both Houk and Rondan were independently working on mechanistic aspects of pericyclic reactions, using a combination of experiment, simple perturbational MO theory and semi-empirical MO calculations as discussed by the authors.
Journal ArticleDOI
Magnetic field polymerisation
TL;DR: In this article, the authors review both theoretical and experimental developments that have occurred in the area of the magnetic field effects upon the chemical reactions and also on properties of polymers synthesised in the field.

TL;DR: In this paper, the effect of magnetic field effects on the intramolecular exciplex fluorescence of a chain-linked phenanthrene (Phen)/N,N-dimethylaniline (DMA) system, Phen-(CH2)n-O(CH 2)2-DMA, has been studied in the magnetic fields (≤0.62 T) as functions of solvent polarity (e = 7.6-36.7), chain length (n = 4-12), and temperature (223-333 K).

TL;DR: In this article, the decay of some radical pairs in micellar solutions under high magnetic fields is interpreted in terms of the relaxation mechanism, and the magnetic field dependence of their relaxation rates is calculated for a model system.
Journal ArticleDOI
Magnetic-field effects on geminate radical-pair recombination
TL;DR: In this article, the spin realignment in the initial radical ion pair is governed by the hyperfine interaction, ΔEhfi, between the unpaired electron spin and the nuclear spins in each radical and by the exchange interaction, J(n), of the radical spins in the pair.

A quantitative interpretation of the magnetic field effect on hyperfine-coupling-induced triplet fromation from radical ion pairs
TL;DR: In this paper, experimentally determined B1/2 values characterizing the magnetic field dependence of molecular triplet production from radical ion pairs originating from photo-induced electron transfer are compared with semi-empirical values obtained according to B 1/2(hfi) = 2(B12 + B22)/(B1 + B2) from the root-mean-square values for the hyperfine coupling of the two radicals, B1 and B2.
