An inexpensive external unit that allows the use of the commercial high-resolution NMR spectrometer for (2)H observation with an (1)H lock system is described. The external unit does not require any tuning, is extremely easy to use, and could be a cheaper and more straightforward alternative to the more expensive (19)F lock configuration. An application for the quantitative determination of the natural isotopic ratio (2)H/(1)H of ethanol and acetic acid is reported.
本文描述了一种价格低廉的外部装置，它能使商用高分辨率核磁共振光谱仪通过¹H锁相系统用于²H观测。该外部装置无需任何调谐，使用极其简便，相较于更昂贵的¹⁹F锁相配置，它可能是一种更便宜且更直接的替代方案。本文还报道了该装置在定量测定乙醇和乙酸的天然同位素比²H/¹H方面的应用。
