Grazing-Incidence Wide-Angle X-ray Scattering (GIWAXS) is a structural measurement technique wherein wide-angle scattering is collected; i.e. large values of the momentum transfer. Because of the inverse nature of reciprocal-space, these large values of q correspond to small distances; WAXS generically probes molecular length-scales.
There is no unambiguous delineation between WAXS and SAXS; generally speaking, WAXS corresponds to angles from approximately 1° to 45°, or q-values from 0.1 Å−1 to 5 Å−1 (6 nm to Angstroms).
Example Data
- Different representations of data from a P3HT thin film
 Data converted to q-space, taking into account the Ewald sphere (notice the 'missing wedge' near the qz axis). |
- A Tungsten-Nickel alloy:
- A thin film of rubrene:
