So what we see is that those six pi electrons are actually going to be de-localized around all six of those atoms.
我们看到,六个π电子会,巡游在所有六个原子周围。

Therefore, electrons cannot be pictured as localized particles in space but rather should be thought of as" clouds" of negative charge spread out over the entire orbit.
因此电子不能描述为空间所处位置的微粒，只能认为负电荷占整个轨道扩散开来的“云”。

Surface plasmon polaritons are a state of evanescent wave, which are localized on the surface of a metal by the interaction of free-electrons and photons.
