Webrelation between line width and life time. I don't see why the following relation should be correct. R s = 1 T s. T s is the time interval between the first and second excitation of the electron. Now, the probability to find the electron in the excited state ρ 22 equals. ρ 22 = τ T s, τ being the life time. Now, I dont understand the following. WebIn 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.
