用固体高分辨核磁共振~(13)C谱、电子自旋共振谱以及X衍射光谱研究了多晶甘氨酸的γ辐射稳定性。结果表明甘氨酸在0—140kGy辐照剂量范围内是稳定的,而~(13)C共振谱线则随着辐照剂量的增加而线性地增宽。
The γ-radiation stability of polycrystalline glycine was studied by solid state high resolution NMR ~ (13) C, electron spin resonance and X-ray diffraction. The results show that glycine is stable in the range of 0-140 kGy irradiation dose while the resonance spectrum of ~ (13) C linearly broadens with the irradiation dose increasing.
