摘　　要：C_(60)与偶氮二异丁基腈热分解产生的游离基(CH_3)_2CCN发生加成反应,产物的红外光谱出现C_(60)和CN,CH的特征振动峰,ESR谱出现一对弱的肩峰,中间的主峰容易功率饱和。表明有两类物种存在。提出了可能的反应机理。The radical adductive reaction of C60 and (CH3)2CCN generated from thermolysis of [(CH3)2C(CN)N= ]2 was reported. IR of the reaction products shown that there had bands of 1429, 527cm-1(C60); 2233cm-1(CN) and 2964, 1369cm-1 (C - H). ESR spectra were composed of a sharp peak with a pair of weak shoulder at g = 2.0032. The main peak appeared power saturation as microwave power increasing, which indicates that there have two kinds of species in the reaction products. The possible reaction mechanism was proposed.
