The mechanism for the ion-molecule reaction of cyclobutene anion with nitrous oxide in gas phase has been characterized in detail.
采用MP2和B3LYP两种计算方法,在6-31++G(d,p)的基组下,对气相中环丁烯负离子与N2O反应的微观机理进行了较为系统的计算研究,并在相同基组下进一步用QCISD方法在MP2优化构型的基础上进行了单点能校正。
2) cyclopentadienylanion
环戊二烯负离子
3) cyclooctatetraenyl dianion
环辛四烯二负离子
4) fullerene anion
球烯负离子
1.
The results showed that many organic species can generate fullerene anions, even though they consist of other non-carbon atoms such as H, O, N, P, but with at least one six-member aromatic ring.
最近又在相同条件下记录了煤、稠环芳香烃等10余种有机物的负离子质谱,发现其中许多物质均能产生球烯负离子,且质谱特征十分相似,与以往观察的正离子质谱有明显不同。
5) frontier molecular orbital:enolate
烯醇负离子
6) tricarbonyltrimethylsilylcyclopentadienyl molybdenum anion
三羰基(三甲硅基)环戊二烯基钼负离子
