1.1本标准包含高分辨率核磁共振（NMR）光谱领域数据表示的基本术语、惯例和推荐做法的定义。一些基本定义适用于宽谱线核磁共振或金属核磁共振，但一般来说，本标准不打算涵盖核磁共振的后一个领域。该版本不包括与双共振或旋转框架实验有关的定义。 1.2以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。

1.1 This standard contains definitions of basic terms, conventions, and recommended practices for data presentation in the area of high-resolution resolution nuclear magnetic resonance (NMR) spectroscopy. Some of the basic definitions apply to wide-line NMR or to NMR of metals, but in general it is not intended to cover these latter areas of NMR in this standard. This version does not include definitions pertaining to double resonance nor to rotating frame experiments. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
