… k H and k D are defined as the reaction rates of each isotope isomer. In many cases, the isotope effect is greater than 1 (normal isotope effect), but there is also an inverse isotope effect, where the ratio is less than 1. The effect when an isotope substitution is made in the bond that is created or broken during the reaction is called the primary isotope effect, and when not, it is called the secondary isotope effect. … *Some of the terminology explanations that mention the "inverse isotope effect" are listed below.

…kH,kDは各同位体異性体の反応速度)で定義される。多くの場合,同位体効果は1より大きい(正常同位体効果)が,比が1より小さい逆同位体効果もある。同位体置換が反応に際して生成・切断される結合になされているときの効果を一次同位体効果,そうでない場合を二次同位体効果という。… ※「逆同位体効果」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 |
