The principle states that the spectral lines of any element include frequencies that are either the sum or the difference of the frequencies of two other lines. An atom can be excited to a higher energy state via absorption of a photon with sufficient energy, or decay to a lower energy state through spontaneous emission of a photon. However, according to the principles of Quantum mechanics, these excitations can only occur at certain energy intervals. The Rydberg–Ritz combination principle helps explain this process. ==History== The spectral lines of hydrogen had been analyzed and found to have a mathematical relationship in the Balmer series. This was later extended to a general formula called the Rydberg formula. This could only be applied to hydrogen-like atoms. In 1908 Ritz derived a relationship that could be applied to all atoms. This principle, the Rydberg–Ritz combination principle, is used today in identifying the transition lines of atoms. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rydberg–Ritz combination principle」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
