Figure 4. Averaged theoretical amide I response of collagen-like peptide for rotation around the main axis of the molecule.

Figure 4

A) Amide I band response of a collagen-like peptide (ID: 1BKV) oriented (φ = 0°, θ = 0°,) plane (i.e. perpendicular to the ZY plane) rotated at different ω angles around the c-axis and its average response. B) Amide I band response of a collagen-like peptide (ID:1BKV) lying in the ZY plane (φ = 90°, θ = 0°) that has been rotated at different ω angles around the c-axis of the molecule and its average response. All graphs are plotted as functions of the polarization angle β of the incident laser beam (according to eq.3).
