4.5H2O中由于离域π键的存在，对紫外-可见光的吸收从紫外区拓展到可见光区，并且在波长为370nm处出现新的吸收峰；

Because of the delocalized π bond , a new absorption peak of ultraviolet absorption spectrum appears at 370 nm .

二氧化氮分子中的离域π键是π4~3而不是π3~3

The delocalized π bond in the nitrogen dioxide molecule is π _3 ~ 4 instead of π _3 ~ 3

对三种化合物的结构进行优化后，从其结构参数可知分子具有刚性平面结构，具有大的离域π键。

After geometries of the three compounds are optimized , it is known that the titled compounds have rigid planar construction and big unlocalized π bond from structural parameters .
