(a) CH functional group images of the sorghum seed tissue from the pericarp (outside), seed coat, aleurone layer and endosperm. Left: visible image. Right: spectra corresponding to the pixel at the cross hair in the visible image. Spectrum pixel size: 10 µm × 10 µm. (b) CH3 anti-symmetric stretch at ∼2960 cm−1; (c) CH2 anti-symmetric stretch at ∼2929 cm−1; (d) CH3 symmetric stretch at ∼2877 cm−1; (e) CH2 asymmetric stretch at ∼2848 cm−1. Left, for (b)–(e): visible image; right: chemical image, peak height of one peak.
