Mixes of sucrose and various proportions of ascorbic acid were irradiated with γ-rays and studied by an electron paramagnetic resonance (EPR) spectroscopy. Before irradiation no EPR signals have been recorded. After irradiation an EPR spectrum of sucrose has been observed from all samples independently of the quantity of ascorbic acid. The influence of the microwave power and the modulation amplitude on the EPR intensity was reported. It has been found that the EPR signal intensity of sucrose decreased when the ascorbic acid is added to it. This result suggests that ascorbic acid play role of free radical scavenger because of its antiradical activity.

用γ射线照射蔗糖和抗坏血酸混合物的EPR研究

用 γ 射线照射蔗糖和各种比例的抗坏血酸的混合物，并通过电子顺磁共振 (EPR) 光谱进行研究。在辐照之前没有记录到 EPR 信号。辐照后，从所有样品中观察到蔗糖的 EPR 谱，与抗坏血酸的量无关。报告了微波功率和调制幅度对 EPR 强度的影响。已经发现，当向其中加入抗坏血酸时，蔗糖的 EPR 信号强度降低。该结果表明抗坏血酸由于其抗自由基活性而起到自由基清除剂的作用。
