Radicals generated by γ-irradiation of malonic acid and methyl malonic acid were studied as a function of temperature by inversion recovery, echo-detected saturation recovery and electron-electron double resonance (ELDOR) at X-band, and by continuou

Electron spin relaxation times obtained by two-pulse spin-echo and Carr-Purcell-Meiboom-Gill (CPMG) experiments were compared for samples with: (i) low concentrations of nuclear spins, (ii) higher concentrations of nuclear spins and low concentration

Electron spin-lattice relaxation times (T1e) for the major radicals in γ-irradiated polycrystalline samples of glycylglycine, l-alanine, 2,4,6-tri-tert-butyl-phenol, and 4-methyl-2,6-di-tert-butyl-phenol were measured as a function of temperature us

A programmable timing unit (PTU) has been designed and constructed having 1 ns resolution and a generalized matrix-based architecture. Automated measurement and calibration of commercially available programmable delay lines achieve the 1 ns resolutio

The effects of methyl rotation on electron spin-lattice relaxation times were examined by pulsed electron paramagnetic resonance for the major radicals in gamma-irradiated polycrystalline alpha-amino isobutyric acid, dimethyl-malonic acid, and L-vali

To understand the signals that are observed under rapid-passage conditions for samples with long electron spin relaxation times, the E' defect in irradiated vitreous SiO(2) was studied. For these samples at room temperature, T(1) is 200 mciro s and T

Electron spin relaxation times of a Nycomed triarylmethyl radical ( sym -trityl) in water, 1:1 water:glycerol, and 1:9 water:glycerol were measured at L-band, S-band, and X-band by pulsed EPR methods. In H 2 O solution, T 1 is 17±1 μs at X-band at
