Abstract

Tightly tracking charge migration Electron transfer dynamics underlie many chemical and biochemical reactions. Erk et al. examined the charge migration between individual carbon and iodine atoms during dissociation of iodomethane (ICH 3 ) molecules (see the Perspective by Pratt). After initiating scission of the C-I bond with a relatively low-energy laser pulse, they introduced a higher-energy x-ray pulse to instigate ionization and charge migration. Delaying the arrival time of the x-ray pulse effectively varied the separation distance being probed as the fragments steadily drifted apart. The experimental approach should also prove useful for future studies of charge transfer dynamics in different molecular or solid-state systems. Science , this issue p. 288 ; see also p. 267
