Even when perceivably identical synthetic procedures are followed, nanocrystal properties, such as the degree of ligand coverage and luminescence, cannot be assumed. This variability was preserved to illustrate the robust nature of the modified Ising model in extracting thermodynamic parameters, and that thorough characterization of each nanocrystal sample is necessary for indepth analyses. X-ray diffraction measurements of dry indium phosphide quantum dots and solvated indium phosphide quantum dots were collected (Figure ). As has been previously reported, an additional peak beyond those assigned to the inorganic reflections is observed at approximately 𝑞 = 1.4 Å !" in the powdered X-ray diffraction spectra that has been attributed to the organic ligands on the surface of the quantum dots. The peak observed in the powder X-ray diffraction of stearate capped nanocrystals (Figure ) is shifted to a slightly larger angle compared to the myristate capped nanocrystals (Figure ). This shift is attributed to smaller spacing between the aliphatic chains caused by the stearate ligands being in a more crystalline phase. 2, 6, 79 X-ray diffraction patterns of solvated colloidal nanocrystals were collected (Figure and 3D) to investigate the structure of the solvated liquid shell; however, solvent scattering resulted in a challenging analysis. By fitting a subtraction of both the diffraction pattern from the neat solvent and the inorganic peaks at fixed reflections, a background subtracted X-ray diffraction pattern was recovered; raw X-ray diffraction spectra (Figure ) and an example fit spectra (Figure ) can be found in the Supporting Information. In solution, the peak attributed to the organic ligands shifts to around 𝑞 = 1.2 Å !" for both the myristate and stearate capped samples and broadens significantly. No difference in the peak is detected between the solvated myristate and stearate capped samples nor between samples before and after treatment with zinc chloride (Figure ).

However, these zero points are sample specific.
