AI Article Synopsis
- The study investigates ultrafast electron transfer in iodomethane and fluoromethane using sophisticated laser techniques at the Linac Coherent Light Source. * The researchers analyze how different UV excitations and chemical properties affect the electron transfer process in both molecules, noting signs of intramolecular charge transfer. * A detailed examination of iodomethane reveals that the distances for effective electron transfer align well with established theoretical models and previous experiments using near-infrared light.
Article Abstract
Ultrafast electron transfer in dissociating iodomethane and fluoromethane molecules was studied at the Linac Coherent Light Source free-electron laser using an ultraviolet-pump, X-ray-probe scheme. The results for both molecules are discussed with respect to the nature of their UV excitation and different chemical properties. Signatures of long-distance intramolecular charge transfer are observed for both species, and a quantitative analysis of its distance dependence in iodomethane is carried out for charge states up to I(21+). The reconstructed critical distances for electron transfer are in good agreement with a classical over-the-barrier model and with an earlier experiment employing a near-infrared pump pulse.
