in the degradation of organophosphorus compounds (OPCs). Unlike the nitrogen analogues CH3 ONO and CH3 NO2 , the experimental data for these two prototypical OPCs are scarce. By high-vacuum flash pyrolysis (HVFP) of the diazide CH3 OP(O)(N3 )2 at 1000 K, the cis and trans conformers of CH3 OPO have been generated in the gas phase and subsequently isolated in cryogenic Ar and N2 matrices for IR spectroscopic
甲氧基次膦氧化物(CH3 OPO)和异构甲基二氧代磷烷(CH3 PO2)是有机磷化合物(OPC)降解的关键中间体。与氮类似物CH3 ONO和CH3 NO2不同,这两个原型OPC的实验数据很少。通过在1000 K下对叠氮化物CH3 OP(O)(N3)2进行高真空快速热解(HVFP),已在气相中生成CH3 OPO的顺式和反式构象体,随后在低温Ar和N2基质中分离得到红外光谱表征。在266 nm激光照射CH3 OPO时,发生顺式→反式构象转化,同时异构化为CH3 PO2。D-,13 C-,
