SUMMARY
The discussion centers on the use of wide-angle X-ray scattering (WAXS) spectroscopy to calculate the pair distribution function, as detailed in the paper "J. Phys. Chem. B 2018, 122, 7616−7624". The study accurately determined the distances to the first coordination shell for low-density amorphous ice (LDA), high-density amorphous ice (HDA), and very-high-density amorphous ice (VHDA) as 2.75 Å, 2.78 Å, and 2.80 Å, respectively. These measurements were achieved through high-resolution data collected at a momentum transfer of 23 Å−1, underscoring the precision of WAXS in characterizing amorphous materials.
