Time-resolved dc photoconductivity has been used to observe quasifree electrons and solvent radical anions in supercritical CO2 (ρc ≈ 0.468 g/cm3; Tc ≈ 31 °C). The electrons have lifetime τe 10 cm2/(V s). For ρ/ρc > 0.64, the product μeτe

Time-resolved pulsed electron paramagnetic resonance (EPR) was used to study spin-polarized mobile H and D atoms in radiolysis of silica glass containing ∼1200 ppm of OH or OD groups. The EPR spectra of the H/D atoms indicate the occurrence of CIDE

Fluorescence detected magnetic resonance (FDMR) is applied to study ion−molecule reactions in squalane (2,6,10,15,19,23-hexamethyltetracosane). Several time-resolved pulsed FDMR experiments are suggested to measure rate constants of scavenging by a

The 100-kHz and time-dependent TR ESR results on the photooxidation of 1,3,5-tris(3,5-di-tert-butyl-4-hydroxybenzyl)-2,4,6-trimethylbenzene (IOH) reveal that two radicals are formed. The experimental observations are consistent with the initial forma
