To determine the crystal structure of a non-cubic crystal using an XRD plot, you will need to perform a qualitative analysis. This involves comparing the peaks in the XRD plot to known patterns of different crystal structures. By matching the peaks in the plot to a specific crystal structure, you can determine the crystal structure of the sample.
An XRD plot of a non-cubic crystal can provide information about the lattice parameters, unit cell volume, and orientation of the crystal. It can also help identify the crystal structure and any impurities present in the sample.
Yes, there are several techniques and methods that can be used to determine the crystal structure of a non-cubic crystal from an XRD plot. These include using the Rietveld method, Pawley refinement, and direct methods. Each method has its advantages and limitations, so it is important to choose the most suitable one for your sample.
The accuracy of the determination of crystal structure from an XRD plot of a non-cubic crystal depends on several factors, including the quality of the sample, the resolution of the XRD instrument, and the chosen method of analysis. In general, the determination can be quite accurate, but it is always important to consider any potential sources of error.
In most cases, it is not possible to determine the crystal structure of a non-cubic crystal using only one XRD plot. This is because the peaks in the plot can sometimes be similar for different crystal structures. It is recommended to collect multiple XRD plots at different angles to improve the accuracy of the determination.
