CrystalDiffract supports drag-and-drop loading of data files, which can correspond to saved diffraction experiments, crystal structure files, or text files containing real diffraction data.ĬIF - including multi-structure files (each structure generates a separate diffraction pattern, within the same window).ĬMTX (CrystalMaker text file: an easy, human-readable format: much safer than CIF!)ĬMDF (CrystalMaker binary crystal file, generated by versions 7 or later for Mac, or version 1 or later for Windows.)ĭirect Simulation Link via CrystalMaker's Transform > Powder Diffraction submenu, including "Live Powder Diffraction" mode.ĬrystalDiffract lets you simulate diffraction patterns from powdered samples, using a choice of X-rays or Neutrons Intensities are calculated using published atomic scattering factors / neutron scattering lengths, which can be viewed and edited in the program's Scattering Factors window. Site occupancy values and any atomic displacement parameters ("thermal ellipsoids") are also used in this calculation.Ĭonstant-wavelength X-ray Diffraction (traditional laboratory source). Intensity as a function of 2θ, d-spacing, 1/d or Q-space (2π/d).Ĭonstant-Wavelength Neutron Diffraction (e.g., reactor source). Intensity as a function of 2θ, d-spacing, 1/d or Q-space (2π/d).Ĭonstant-Wavelength Electron Diffraction (e.g., powder rings in a transmission electron microscope). Intensity as a function of 2θ, d-spacing, 1/d or Q-space (2π/d).Įnergy-Dispersive X-ray Diffraction, (synchrotron source). Intensity as a function of energy, d-spacing, 1/d or Q-space (2π/d). Time-of-Flight Neutron Diffraction (neutron spallation source). Phase transition visualized using 'Spectrum Colours' option The Search field in action: the 004 peak is shown and (if the Reflexions List is open) its list row is highlighted. Intensity as a function of time-of-flight, d-spacing, 1/d or Q-space (2π/d). CrystalDiffract 6 program interface showing a three-phase mixture plotted with other patterns, and with screen tools visible. You can also export the entire diffraction pattern, reflection list, structure element plus crystal structure data in CIF or CMTX format. Wavelength (angle-dispersive diffraction)ĭetector 2θ Angle for energy-dispersive and time-of-flight simulations. CrystalDiffract allows you to save your work as a standalone document, for quick and convenient access the next time you use the program. Instrumental Peak Broadening: constant values for constant-wavelength and EDX simulations variable broadening for time-of-flight neutron diffraction according to the specified instrument resolution (Δd/d) Peak Profile: Lorentzian, Gaussian, Pseudo-Voigt (variable eta), Delta Neutron Flight Path: total distance, in metres, for time-of-flight simulation. Zero Correction plus intensity offset and scale factor (for observed datasets).īackground Function. CRYSTALDIFFRACT SPACE GROUP DETECTION FAILED PLUS Users can specify a background function by editing control points in an easy and intuitive manner. The background can be toggled on or off at any time. Intensities can be displayed on either a linear (default) or logarithmic scale. CRYSTALDIFFRACT SPACE GROUP DETECTION FAILED PLUS.
