FSD amide I spectrum of the EC-BLG complex at mr = 7.5. The experimental FSD data are reported as filled squares and the continuous line is the best fit to data with Gaussian lineshapes. The single secondary structure contributions are reported as filled curves, together with the EC bare spectrum (dotted line). The dashed line at low frequency is the tail of the amide II absorption band.
