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 … See more Normal distribution If the considered function is the density of a normal distribution of the form Other distributions In spectroscopy half the width at half maximum (here γ), … See more • Gaussian function • Cutoff frequency See more • FWHM at Wolfram Mathworld See more WebSep 18, 2015 · The half-width at half-maximum of a square root of Lorentzian fit function yields γ=2.7±0.2 meV.
