Abstract:
We report experimental results on x-ray diffraction of quantum-state-selected
and strongly aligned ensembles of the prototypical asymmetric rotor molecule
2,5-diiodobenzonitrile using the Linac Coherent Light Source. The experiments
demonstrate first steps toward a new approach to diffractive imaging of
distinct structures of individual, isolated gas-phase molecules. We confirm
several key ingredients of single molecule diffraction experiments: the
abilities to detect and count individual scattered x-ray photons in single
shot diffraction data, to deliver state-selected, e.g., structural-isomer-
selected, ensembles of molecules to the x-ray interaction volume, and to
strongly align the scattering molecules. Our approach, using ultrashort x-ray
pulses, is suitable to study ultrafast dynamics of isolated molecules.
