including neutral and ion decomposition difference (NIDD) mass spectrometry; the latter allows for the examination of the neutrals' unimolecular reactivity. Further, the anionic, the singlet and triplet neutral, and the cationic [C3′H4′O] •-/0/•+ potentialenergy surfaces are calculated at the B3LYP/6-311++G(d,p) level of theory. For some species, notably the singlet state of oxyallyl, the theoretical treatment
五种不同的阴离子 [C3'H4'O]•- 异构体,即丙烯醛、乙酰卡宾、甲酰甲基卡宾、甲氧基亚乙烯基和氧基烯丙基的自由基阴离子在离子束质谱仪中生成并进行中和-再电离 (NR)质谱实验,包括中性和离子分解差异(NIDD)质谱;后者允许检查中性的单分子反应性。此外,阴离子、单线态和三线态中性以及阳离子 [C3'H4'O] •-/0/•+ 势能面是在 B3LYP/6-311++G(d,p) 理论水平计算的. 对于某些物种,特别是氧烯丙基的单线态,理论处理由 G2、CASSCF 和 MR-CI 计算补充。
