Fig. 2From: Localization of polyhydroxybutyrate in sugarcane using Fourier-transform infrared microspectroscopy and multivariate imagingFourier-transform infrared spectrum of poly[(R)-3-hydroxybutyric acid]. Vibrational modes and spectral assignments are provided in Table 1. The spectrum was collected using 256 scans and a 128 × 128 focal plane array detectorBack to article page
