Access to the ICDD (international Centre for Diffraction Data) Powder Diffraction Files (PDF-4)

Access to the ICDD (international Centre for Diffraction Data) Powder Diffraction Files (PDF-4) is restricted to UCI users only - users must go to Computer #563 in the Science Library Grand Reading Room (2d floor). That single computer with this database can be reserved for increments of 30-120 minutes using the Library Reservations system at https://spaces.lib.uci.edu/reserve/powder/

PDF-4 contains 480,000+ entries combining the world's largest sources of inorganic diffraction data from crystals and powders ina single database. There are 134 display fields coupled with 80 searches and the database is designed to support automated quantitative analyses by providing key reference data required for these analyses featuring digitized patterns, molecular graphics and atomic coordinates. These features incorporated in PDF-4+ enhance the ability to do quantitative analyses using third party software by any of three methods
