Summary on Grant Application Form
Being able to probe structural (electronic and geometric) change on the timescale of atomic motion

(femtoseconds) offers the most direct route to understanding the structure-function relationship in

chemistry, which underpins much of modern technology. Here, we propose the conceptually novel

method, Time-resolved Intramolecular Photoelectron Diffraction (TIPD), in which photoelectrons are

diffracted from negatively-charged functional groups in a mass-selected gas-phase polyanion. The

measured interferogram contains structural information about the location of charge-sites relative to

the molecular orbital from which an electron is detached. It can be measured with sub-100 fs

resolution to enable real-time probing of photoinduced processes including charge-transfer

processes and structural transformations in, for example, proteins and conducting polymers.
