Raman data can also be loaded via established data-loading tools in Python. For instance, one can use pandas' csv loader to load a spectrum from a .csv file with two columns storing the intensity data and the spectral axis by using: import pandas as pd data = pd . read_csv ( csv_filename ) raman_spectrum = ramanspy . Spectrum ( data [ " < intensity_column > " ] , data [ " < axis_column > " ])
