The quantum mechanical basis for its formulation was first worked out by physical chemist N. Colin Baird in 1972. A lowest triplet state of cyclic ring molecule follows Baird's rule when the number of its π-electrons equals 4''n'' where ''n'' is any positive integer. However, in most cases the lowest triplet state of cyclic ring has higher energy then the lowest singlet state of cyclic ring due to Jahn–Teller effect. ==See also== * Möbius–Hückel concept * Möbius aromaticity * Hückel's rule 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「Baird's rule」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.
