环庚烷

利用金刚石对顶砧（DAC）装置产生高压，在室温下对环庚烷进行了高压原位拉曼光谱研究。

In situ Raman spectra of cycloheptane have been characterized under high pressure generated by diamond anvil cell ( DAC ) at room temperature .

而环庚烷正离子的重排则是环的缩小过程，在缩环过程中，经历了两个过渡态；

Whereas the rearrangement of cycloheptane cation was a process of ring-reducing which had two transition states .

苯基多烯为共轭桥比二氮环庚烷具有更高的分子内电荷转移效率。

It has shown that the Phenyl-polyene as conjugated bridge can improve the efficiency of charge transfer while pyrazine reduces molecular susecptibility .

加入少量的萘、蒽等稠环芳烃于庚烷溶剂中，则大大提高高聚物的分子量。

Addition of small amount of polynuclear hydrocarbons , such as naphthalene or anthracene to the heptane polymerization solution raised the molecular weight of the polymer to a considerable extent .
