According to ESR spectra of the radical - probe I it has been shown that there are two regions in cotton cellulose: ordered and disordered ones, pointing to inhibition and free rotation of the radical. 40 spin-labeled samples of cotton filaments and their mutants by the radicals II-IX chemically bound by the cellulose hydroxyl group were obtained. From ESR spectra strong inhibition of iminoxyl radical was established which was the evidenced of high rigidity of disordered regions of cellulose. Conformational changes of cotton cellulose grown from seeds exposed to different doses of gamma-irradiation.
根据自由基探针I的电子自旋共振光谱表明，棉纤维素中有两个区域：有序区和无序区，这表明自由基受到抑制并能自由旋转。通过纤维素羟基化学键合的自由基II - IX，获得了40个棉纤维及其突变体的自旋标记样品。从电子自旋共振光谱确定了亚胺氧基自由基受到强烈抑制，这证明了纤维素无序区域具有高刚性。研究了暴露于不同剂量γ射线的种子所生长的棉纤维素的构象变化。
