- The folder "Data" containts the raw spectra. For each of the measured binary mixtures there is a subfolder with the respective mixture name. 
Within the subfolders are the .txt files, each containing the measured spectrum for the respective composition. 
The file "ramanshift" contains the corresponding Raman shift in cm^-1 for all spectra.
- The folder "Code" contains the Python codes for data evaluation and 
visualization:
O "ReadSpecData" reads the data from the .txt files 
into a Pandas DataFrame, then the spectra are processed according to 
method A and B as described in the publication. The functions for spectra
processing are imported from "spec_functions". Finally, the figures showing spectra
shown in the publication are generated. The DataFrame is pickled.
O "absolute_to_normal_intensity" converts the intensities obtained from 
method A into molar intensities. Therefore, the pickled data are read,
literature data for refractive index and density from "refractive_index_density" 
are read and processed. Finally, the figures showing intensities
shown in the publication are generated.

!!! Before you run the code, modify the pathnames in "Read_spec_data"
and  "absolute_to_normal_intensity" so that it matches the directory where you saved 
the corresponding files !!!
