WebMay 28, 2024 · The full width at half maximum (FWHM) is the width of a line shape at half of its maximum amplitude, as shown below: A closely related quantity is the half width at half maximum (HWHM) or the Resolving Resolution and it is half of the FWHM. For Gaussian line shapes, the FWHM is about 2.4 standard deviations. Why is the FWHM of XRD … In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum curve measured between those points on the y-axis which are half the maximum amplitude. Half width at half maximum (HWHM) is half of the FWH…
