We were able to analyze the absorbances of five samples of alcohol: gin, whiskey, light tequila, dark tequila, and grain alcohol. Interestingly, absorbance peaks were similar for gin, light tequila, and grain alcohol (samples 1, 4, and 5, respectively); both whiskey (2) and dark tequila (3) had unique absorbance spectra:

The absorbance data correlates with qualitative observations of color:

We will analyze the data and create a song to present to the class.
