Fig. 8From: Raman spectroscopy enables phenotyping and assessment of nutrition values of plants: a reviewTop: Raman spectra collected form hemp (green), GC (purple), TCC (blue) and TS (red). Bottom: Raman spectrum of THCA extract (maroon). Spectra normalized on CH2 vibrations (1440 and 1455 cm−1) that are present in nearly all classes in biological molecules (marked by asterisks (*)).
