...This is called a band spectrum. The above are examples of absorption spectra, but when a molecule moves from its ground state to a higher energy state due to gas discharge or light irradiation, and then transitions back to the original ground state, an emission spectrum is observed. For example, fluorescence and phosphorescence spectra are emission spectra due to transitions between electronic states. ... *Some of the terminology that refers to "emission spectrum" is listed below.

…これを帯スペクトルband spectrumと呼ぶ。以上は吸収スペクトルの例であるが,気体の放電や光照射によって分子が基底状態からいったんエネルギーの高い状態に移り,再びもとの基底状態に遷移するとき,発光スペクトルemission spectrumが観測される。たとえば,蛍光スペクトルやリン光スペクトルは電子状態間の遷移による発光スペクトルである。… ※「emission spectrum」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
