Figure 4: A representative Fourier self-deconvolution analysis applied to the spectra of lysozyme in D2O solution. A significant increase in intensity of α-helix component was observed after 4 h of exposure (the red lines refer to exposed sample spectra). Increases in -sheet and -turn structures around 1635 and 1685 cm−1, respectively, (both localized by arrows) were evidenced after the exposure, as well.
