P2D2 = Predicted Powder Diffraction Database


Content

I - Introduction

II - Data from ZEFSA-II

III - Data from GRINSP IV- P2D2

The P2D2 (Predicted Powder Diffraction Database) contains the powder diffraction patterns calculated from these structure candidates, allowing for search-matching.



I - Introduction

The PCOD [1] (virtual compounds), a subset of COD [2] (real compounds), contains CIFs of inorganic structure candidates from mainly two sources (computer programs) : ZEFSA-II and GRINSP.
