downfield
Gujianhan 的解释很清楚.但您没想过既然 upfield 是高磁场,downfield 就是低磁场吗?
在重稀土化合物的化学位移研究,就有共振谱线移向高场和低场之分;在核磁共振位移性能的研究里,也有高磁场位移(upfield)与 低磁场(downfield)的区别.

upfield是高磁场的意思,请问downfield也是高磁场的意思吗?
不是这样的。在英语指示平面的方位词里面,down和up确实有些混淆,例如go down the street,go up there,都可以指同一个方位,upfield和downfield也都有“在前场“的意思。但是对上下方位以及其他的词汇而言,down和up还是区分的很严格的。所以upfield 是指高磁场,并非等于downfield也是同样意思。

四甲基硅烷低磁场。
在重稀土化合物的化学位移研究中,有共振谱线移向高场和低场之分;在核磁共振位移性能的研究里,也有高磁场位移(upfield)与 低磁场(downfield)的区别。
四甲基硅烷的12个氢是相同的,4个碳也是均等的,这样四甲基硅烷在1H谱中和完全去耦的13C谱中均呈现一个单峰,而目前几乎所有可用1H谱和13C谱研究的化合物的化学位移都在四甲基硅烷峰的低场处(即化学位移更大处)。
