Hi. I'm looking the dimensions that are giving on this graphic on the "X" axis, as they are not giving it on 2(Theta) degrees. Can you help me to solve this and how to convert it to normal 2(Theta) degrees. Tx
to my opinion the x-scale is just the consecutive numbering of the measurement points of the XRD pattern for each theta (2theta) position of the diffractometer.
Without further knowledge, such as for example the starting theta/2theta and the angular step width, you will not be able to attach a 2theta scale here.
Even in the case that you know a) the sample material and b) you may be able to identify some peaks, you have to know c) the x-ray wavelength for the reconstruction of the angular scale.
I also don't think you can resolve this without help from your operator. These could also be angular minutes (60 angular minutes=1°) or the data import tool simply cropped away the . from the numbers and you have to divide by 100 to get to °. With the variety of these options and the ones Gerhard Martens mentioned, you need internal help, not external.
