Figure 1.

FTIR spectra of dried peptides 1–6, unexposed (A, samples a) and irradiated for twenty four hours (B, samples e). Sample numbers correspond with peptide numbers: peptide 1 is shown in samples 1a and 1e, peptide two in samples 2a and 2e, peptide three in samples 3a and 3e, peptide four in samples 4a and 4e, peptide five in samples 5a and 5e, and peptide six in sample 6a and 6e. The circles in the spectra represent the data range that changed during exposure.
