(A) 1D-IR (FTIR) spectra, (B) the 1685 cm−1 to 1620 cm−1 absorbance peak ratio, (C,D) 2D-IR spectra, (E) diagonal slices (along the yellow lines in (C) and (D)), and (F) slices at νpump = 1620 cm−1 (along the blue lines in (C) and (D)) for αS fibrils aggregated with different concentrations of NaCl. Lines through the points in (E,F) are Catmull-Rom splines.
