Abstract

With the Powder Diffraction File (1988), twelve different numerical search manuals with the number of entries per phase from one to four were used to identify the 237 experimental X-ray powder diffraction data sets collected from visually measured 57.3 mm diameter Debye-Scherrer films. Eighty-four percent of the experimental X-ray powder diffraction data have the same strongest reflection as the data in the Powder Diffraction File. For a single-phase unknown the most efficient numerical search manual type is a single entry per phase if used correctly and systematically; however, multiple entries do help in some instances. Up to seven groups must be searched in a single-entry numerical search manual to identify a phase.
