Effect of electron scavengers on the yield of electrons in shallow and deep traps at 77 K

Conduction, breakdown and electronic-ionic phenomena in liquids

“…They found that while the rate constants for scavenging hydrated electrons by Cd++ in H 2 0 and D 2 0 are the same, its efficiency for scavenging dry electrons in D 2 0 is 47% greater than in H 2 0. In a methanol/water glass at 77 K, Moan et al (122) found that with the exception of H+, a variety of electron scavengers reduced the yield of electrons in shallow stable traps much more efficiently than that of electrons in deep traps. The results were accounted for by assuming that the major part of scavenging occurs by electron tunneling from the traps rather than by capture of mobile electrons.…”
