Structure

Raw ATR-FTIR data is contained in the IR_data_.. folders, while DS values from different methods are found in the respective .txt files.
> Note: IR_DS refers to the integration based method reported in https://doi.org/10.1002/pol.20230220

Methods

For more information on data generation and analytical setups please refer to the original publications referenced above. DS data based on 1H NMR data is obtained according to the newly reported evaluation routine.
