FWHM & XRD

    Why is FWHM taken for calculations in XRD analysis of powder pattern? I mean, why don't we take the full peak value?

    They are two different things. The peak value gives you the height of the distribution. The FWHM gives you a measure of the width of the distribution.

    Thanks a ton for your reply . But what i want to know is why do we take the width for calculations and not the height

    For what kind of calculations? Can you give an example?
