Figure 3.

Deconvolution of UV–Vis absorption spectra of iodine-stained NaCl fibrils (a), SDS fibrils (b), and no-salt fibrils (c). In all panels, black and red solid lines represent the experimental and reproduced spectra, respectively, and the experimental spectra are the same as those shown in Fig. 2b. Six Gaussians represented with dashed red lines or filled areas correspond to absorption bands obtained by the deconvolution using Eq. (1), and dashed black lines represent baselines derived from scattering of the sample fibrils. The wavenumber of each absorption band is labeled.
