generation, identification, and characterization of the phenylselenyl radical using the matrix isolation technique in combination with density functional theory (B3LYP/cc-pVTZ) computations. The hitherto unknown phenylselenyl peroxy radical was synthesized by co-condensation of the phenylselenyl radical with molecular ground state triplet oxygen from the gas phase and subsequent trapping in argon matrices at
当前的研究重点是结合基质功能分离技术和密度泛函理论(B3LYP / cc-pVTZ)计算,对苯基硒基自由基进行生成,鉴定和表征。迄今未知的苯基硒烯基过氧自由基是通过将苯基硒烯基自由基与气相中的分子基态三重态氧共缩合,然后在10 K下捕获在氩气基质中而合成的。实验的红外光谱(包括18 O同位素标记的材料)与从B3LYP / cc-pVTZ计算获得的数据。在312 nm辐射下,苯基硒烯基过氧自由基会异构化为热力学更稳定的同等新型苯基硒烯酰基。
