| 摘 要： | 采用变温红外光谱法对高能钝感炸药1,1-二氨基-2,2-二硝基乙烯(FOX-7)α→β和β→γ两种晶型转变进行了研究,讨论了FOX-7相变过程中的分子间氢键作用和分子结构.55 ～122℃,v11NH2(vas)]和v10NO2(vs)]频率移动为20 cm-1左右,v18C-NO2(v)]消失;122 ～190℃,v12C-NH2(v)]消失,v20NO2(ω)]转变为新的宽峰.红外光谱结果表明:在FOX-7相变过程中,分子间氢键作用发生改变,分子结构改变.此外,随着温度的升高,在α→β的相转变中,氢键长度变化不符合线性热膨胀公式,并且v11、v4NH2(vas)与2v5NH2(γ)的费米共振]、v7NO2(vas)]和v10等谱带表现出与α-和β-FOX-7均不同的特征频率,表明FOX-7在α→β相变过程中要经历一种过渡态.
