Appendix 1. Revised FTIR Algorithm for Functional Group Identification FTIR spectra were analyzed using a revised algorithm for baselining and spectral smoothing,fitting overlapping peaks, and integrating absorbance before converting to mass with standardcalibrations. Table S-1 summarizes the regions and parameters used in the algorithm. Baselining and spectral smoothing. A third-order polyn
