Raman scattering spectra --> Out-of-phase ("Imaginary") component of the Raman susceptibility.
This C++ program takes a file with Raman spectrum (Wavenumber and Raman scattering intensity) and a specified temperature. It first checks that the input file has the right format (2 columns) and that there is no missing data. It then reads each wavenumber and intensity into a customly-declared datapoint structure. The intensity is scaled based on the Bose Einstein (BE) distribution for the temperature and each wavenumber (frequency). The scaled intensity is output to a file. An example input file "Bi25FeO39.txt" is provided. An input file with improper data is also provided "Improper_datafile.txt".
Compilation: g++ -std=c++11 BoseCorrection.cpp -o bc.exe
Execution syntax: bc.exe < Input_Filename > < Temperature > < Output_Filename >
Execution example: bc.exe Bi25FeO39.txt 373 output_file.txt
