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… WebIUPAC further offers a peak-width definition for mass resolution. “For a single peak made up of singly charged ions at mass min a mass spectrum, the resolution may be expressed …
