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… WebFT-IR can be used for identification purposes in forensics, plastic recycling, failure analysis, quality control, and much more. FT-IR can also be used to quantify components in a sample made of more than one substance. …
