核磁共振法(简称NMR法)用于动力学研究的主要特点是在平衡态下测量反应速度参数,因此NMR法对某些分子平均寿命τ=1～10-~3sec的快速可逆反应速度参数测量有独到之处,本文用目前很多“高校”所具有的60MHz JNM-PMX60Si型核磁共振仪测量丙酮酸水合反应速度参数,该实验荟集了NMR法测量动力学参数的主要特点,所测数据比较稳定可靠,为此本文在实验的基础上将该实验介绍给读者参考。
The main feature of the NMR method used in kinetic studies is the measurement of reaction rate parameters in an equilibrium state. Therefore, the NMR method measures the fast reversible reaction rate parameters of some molecules with an average lifetime of τ = 1 ~ 10 ~ 3sec In this article, we use the 60MHz JNM-PMX60Si nuclear magnetic resonance (NMR) instrument which is currently used by many colleges and universities to measure the pyruvate hydration reaction rate. The experiment is a collection of the main features of the NMR method for the determination of kinetic parameters. The measured data are compared Stable and reliable, this article based on the experiment introduced to the reader for reference.
