Fast Passage

The spin–lattice relaxation time T1 of electrons (et−) trapped in several ice matrices at 77 °K has been estimated to be of the order of 10−2 s by observation of the electron spin resonance (e.s.r.) dispersion signal under fast passage conditions. These studies, together with measurements of the microwave power saturation of the e.s.r. absorption signal indicate that there is little difference in T1 at 77 °K for et− in solute-free polycrystalline H2O or D2O ice, γ-irradiated 8 M NaOH/H2O or NaOD/D2O glassy ices, and in 8 M NaOD/D2O glasses in which the electrons were produced by photoionization of ferrocyanide ion. This indicates that the predominant spin–lattice relaxation mechanism is not cross relaxation, and that correlations between T1 and line width or trap depth are inappropriate.
