Pressure jump method

Japanese: 圧力ジャンプ法 - あつりょくじゃんぷほう
Pressure jump method

...This is a method developed by M. Eigen of Germany, and its measurement principle is to rapidly change the temperature or pressure of a reaction system in equilibrium, creating a non-equilibrium state, and then to measure the process by which the system approaches a new equilibrium state in order to determine the reaction rate. This method is also called the temperature jump method or pressure jump method, and can measure reaction rates with half-lives of 1 to 10 -6 seconds. The relaxation method was used to measure the reaction rate of the neutralization reaction of an acid and a base in water, H 3 O + +OH - - → 2H 2 O, for the first time. ...

*Some of the terminology used in reference to the "pressure jump method" is listed below.

…これはドイツのM.アイゲンにより開発された方法で,その測定原理は,平衡状態にある反応系の温度あるいは圧力を急速に変化させることにより,非平衡状態とし,系が新しい平衡状態に接近する過程を測定し,反応速度を決定しようとするものである。この方法は温度ジャンプ法,圧力ジャンプ法などとも呼ばれ,これらの方法により半減期が1~10-6秒の反応速度を測定することができる。緩和法により,水中での酸と塩基の中和反応 H3O+OH―→2H2Oの反応速度が初めて測定された。…
