To demonstrate the applicability of the rwsLSSA routine with the experimental data, we chose acenaphthene, for which recent experimental data are available. There are several structural refinement results based on either purely GED data or purely on the microwave (MW) spectroscopy results, but also combined analysis based on both types of gas-phase FIG. . Experimental sM(s) curves for acenaphthene. These curves are for the GED+MW(IV) model. structural data (GED+MW). We took the experimental sM(s) curves from one such model (Fig. ) and the refined molecular parameters from the best fit (model GED+MW(V)). The refined molecular model was used to calculate the model RDF, which represents the best available representation of the molecular signal. In the experiment, there are actually two experimental sM(s) curves that correspond to two independent measurements from the two different sample-to-detector distances, denoted as long distance (LD) and short distance (SD). The LD measurements allow to cover the small range s-space, whilst the SD results provide information on the large-s diffraction patterns (Fig. ).
