New Capabilities for 2026
To enhance the value of the PDF® Databases, ICDD has incorporated many new developments for the 2026 product release. Every year, we listen to our customers to create a better product for you. Below are some value-added developments designed to make the ICDD products more functional and powerful for 2026.

Calculated Intensities Scaled to 100%
- For historical reasons, intensities for calculated diffraction patterns were scaled to 1000 using integers
- Now intensities are scaled to 100% using floating-point numbers
Simulate 2D Ring Patterns from CIFs*
In addition to simulating 2D ring patterns from PDF entries, 2D ring patterns can now be simulated from a user-imported Crystal Structure *.cif file.
*Only available in PDF-5+ and PDF-4 databases
Thermal Ellipsoids*
Thermal ellipsoids for selenium sulfide
For PDF entries that have anisotropic thermal displacement parameters, thermal ellipsoids can be displayed in the 3D structure viewer.
*Only available in PDF-5+ and PDF-4 databases
New SIeve+ Features
- Combine the search history with common filters
- Deep Search option
- When selected, the current search will use all the permutations of 8 strongest search peaks to 3 strongest database peaks (instead of just the strongest database peak)
- New X-axis range option
- Full Range
- Restrict Range (to experimental data)
- Hide phase plots using checkboxes*
- Import 2D diffraction patterns from ESRF files (*.edf)*
- Simplified sector integration with 2D diffraction patterns*
*Only available in PDF-5+ and PDF-4 databases
New Raman Features
- Raman Analysis Graph*
- The user can import Raman spectra from a file and add Raman spectra from the PDF database into a graph for visual analysis
- Raman-Diffraction Search*
- An option has been added to the Raman search that will only include Raman entries that are cross-referenced to X-ray diffraction data
- New Raman Display Fields*
- Literature reference
- Database comments
*Only available in PDF-5+ and PDF-4 databases
