Figure 3

FSD spectra of the EC-BLG complexes at selected mr and of epicatechin in the Amide I region. In the panel (a) the vertical lines correspond to the central frequencies of the most intense contributions reported in Table 1. The star marks the presence of the EC absorption band at 1595 cm⁻¹. In the panel (b) the FSD absorption spectrum of 7.5 mM EC in D₂O buffer solution is shown.
