FTIR maps from the same location on an environmentally inoculated sample. Each map shows the intensity of infrared reflection at a distinct wavelength. Panel A shows the 1516 cm⁻¹ band associated with the C-C aromatic stretch, panel B shows the 1660 cm⁻¹ band associated with the Amide I, panel C shows the 2959 cm⁻¹ band associated with the CH₃ functional group, and panel D shows the combined false colour FTIR map of these three bands.
