(1)的紫外谱在232. 5nm和313nm有吸收，相对于阳离子发生了

The ultraviolet spectrum of (1) has absorption at 232.5nm and 313nm, and has a red shift relative to the cation, but it is very different from the tropatriene cation. This once again confirms that the product is the delocalized system of (1). Similarly, the non-delocalized (6) is added with HSbCl6 to generate (7), and its NMR spectrum shows that it has a delocalized structure.

(1)的紫外谱在232. 5nm和313nm有吸收，相对于阳离子发生了红移，却与庚三烯阳离子差别很大，这再一次印证了产物为(1)的离域体系。同样，不离域的 (6)加入HSbCl6生成的 (7) ,其NMR谱表明它具有离域结构。

(1) The UV spectra of (1) were absorbed at 232.5 nm and 313 nm, which showed a red shift compared with the cation of heptadiene, which confirmed that the product was a delocalized system of (1). Similarly, the NMR spectra of (7) produced by adding hsbcl6 to (6) which is not delocalized indicate that it has delocalized structure.<br>
