Using powder X-ray diffraction to analyse a metal compound, a simple pattern of peaks resulted, where the largest peak existed at an angle of 2θ= 19.8°. However, when a similar sample was analysed that contained a metallic impurity, this 2θ value became 22.4°. What does this suggest is happening to the crystal lattice and why?

a) you observe that an X-ray diffraction pattern has a strong peak at 2 theta=100.7 degrees. using the following facts, calculate the d spacing for this peak (given-wevelenght xray=0.154nm,sin100.7=0.98,sin50.35=0.77 b) How many atoms are in a Hypothetical diamond cubic structure with double the number of internal atoms and superimposed body centered cubic atom c) Calculate the packing factor for face centered cubic crystal that has a centeral impurity atom that fills the interstitial space

Assume that an X-ray diffraction pattern is taken from two specimens of pure Ni. The two specimens are identical except that one contains numerous twins, while the other is untwinned. Would the XRD patterns show a larger number of diffraction peaks for the specimen containing the twins? Explain the reasoning behind your answer.

how exactly do you determine the miller indices for the first three peaks of a diffraction pattern? for cubic it makes sense for it to be (100) (110) (111) but for less symmetrical structures how do you determine which planes will have the lowest values. Specifically for structures such as tetragonal, rhombohedral and orthohrombic.
