| 摘 要： | 采用紫外-可见光谱、X-射线光电子能谱、电子自旋共振谱及质谱等实验手段研究了固态含能材料六硝基菧（HNS）在365 nm紫外光照下的光解机理。HNS的乙腈溶液被紫外光照射后，在310 nm和350 nm处出现了两个新的吸收峰。X-射线光电子能谱实验中，N元素和O元素的窄谱图分别在401 eV和528 eV处出现了新峰。质谱分析则显示在质荷比403和329处出现了两个新的特征离子峰。实验结果表明：CNO2键断裂、分子中NO2基团异构化为亚硝基，以及随后的NO消去等过程均可能发生在六硝基菧的紫外光解反应过程中。

| Abstract: | The ultraviolet (UV) photodecomposition of solid HNS (2, 2, 4, 4, 6, 6-hexanitrostillbene) under irradiation of UV light has been studied by different experimental means, including UV-Vis spectra, X-ray photoelectron spectroscopy (XPS), electron paramagnetic resonance spectra (EPR) and mass spectra (MS). Two new peaks locating around 310 nm and 350 nm appear in the UV-Vis spectra of HNS/acetonitrile solution after UV light irradiation. Similarly, after laser irradiation, two new peaks appear at the binding energy of 401 eV and 528 eV for N 1s and O 1s XPS narrow scan spectra, respectively. Furthermore, the mass spectrum shows two new characteristic ion peaks corresponding to mass-charge ratio of 403 and 329. Experimental results indicate that CNO2 broken and nitro-nitrite isomerization with subsequent release of NO are the main photolysis pathways during the photodecomposition of HNS. |
