The FTIR spectra of beer samples in the characteristic range between 926 and 1481 cm 1 clearly include two abnormal spectra, which could be identified as a beer mixed with lemonade and an alcohol-free beer erroneously integrated into the sample set. The constant ϵ ϵ is called molar absorptivity or molar extinction coefficient and is a measure of the probability of the electronic transition. Due to the lack of any fine structure, spectra are rarely shown in their raw form, rather, the peak maxima are simply reported as a numerical list of “lamba max” values or % max %3) The visible region extends from 400-800nm. The small molecules (<1000 Da) are referred to as the beer metabolome and play an important role in beer characteristics such as taste, aroma, yeast fermentation, foam stability, or beer ageing.
